Title: turrning a 300 Rum into 30-378 wby whats needed
Post by: 257wbymagkiller on January 04, 2016, 06:50:51 PM
So im thinking about taking  my Rem 700 PSS in 300 RUM and turnning it into a 30-378 wby, what all is needed to do so it will be my first bolt gun build.

I know barrel, and bolt but is that all thats needed?

Go easy on me here guys

Or maybe even a 7mm wby or 270 wby id consider turnning it into

.........and 30-378 ammo is around $150 a box. No thanks. I've wanted one myself, but just can't bring my self to spending that much for a box of 20.

Why would you want to the numbers between a 300 rum and the 30 378 are not that far off, and like Campmeat said the ammo is way more expensive. besides you already have a great gun. :twocents:

:yeah:

Why are you wanting to change barrels and cartridge? Is it not accurate enough? If that's the case, have a gunsmith do some minor work on the existing rifle.

I don't know the length of both cases or the diameter of either off the top of my head but if the rum is smaller in both accounts and the barrel has the correct twist rate all you would need is a reamer. It would be like turning a 7mm rem mag into a 7mm stw


Might post this is the gun section  :twocents:

The gun is very accurate. I have 2 300 RUMs now and would like to and to the weatherby  line I have going.

I know 30-378 iso not cheap at all but sure is fun.

7mm wby and 270 wby have always been on my hit list so I figured why not build on out of the 700 PSS and keep the 700 long range that's brand new.  :dunno:

So would you guys do the 7mm wby or the 270 wby??

Probably should should be in the gun section. Good call.

Re-barrel it to a 30-30, and keep your shots ethically within 50 yards.

Oh, sorry, wrong thread.

I just thought that as long as everyone was telling you that you don't want what you said you want that I'd chime in.

Happy New Year.      :IBCOOL:

I have reloaded for both. The 300 rum was more efficient. If you want to have fun, turn the 300 rum into a 338 edge.

If I were in your place I think I would sell one rum and buy a weatherby mark 5 used. Cabelas in Lacey has a couple in 30-378. The accumarks I have been around have all been great shooters!

180 grain accubond and ballistic tips. Both had the same poi and the bt's grouped better at longer ranges.

the wby may outshine the rum with heavier bullets but not the case with the 180's

These are accuracy load numbers with your rifles?
I like posts like this, real life experience trumps published load data any day of the week.
I helped with load development on a 338-378 and 300 bergers. Could punch them real fast but accuracy wasn't there. Ended on a 2800 ish fps load for accuracy in that case.

Yes. Both loads were very accurate. I could shoot sub Moa 3 shot groups consistently with both loads.

Not sure why you'd want to turn a hot-rod .30 cal into another hot-rod .30 cal if you're looking for something different.

I'm with haugenna, a .338 Edge would be fun, and different than what you already have.

I shoot a 300 RUM and hunting partner has a 30-378.  We are working on loads now to make the factory Weatherbey loads less expensive, and I am just trying some different powders and bullets in my RUM.  If I were ever looking to hot rod my 300 RUM, the 338 edge would be the platform I would move to because the cost to do so is very affordable.  New barrel, reamer by gun smith, longer box mag, and dies and load development.  I am sure I missed something, and would actually provide the hot rod gains you are looking for.  Long heavy bullets flying at ridiculously fast speeds.  Very economical upgrade for what you are trying to do.

I would go with the .338 Edge and the Berger 300gr OTM's. The 300's shot well for me in the Edge along with the Hornady 285gr BTHP.

Easy to reload for, I just used RCBS .338 Ultra magnum dies and it still performed under half MOA with a 30" Benchmark barrel.

On this one I had Benchmark barrels do all the work. Give Chris a call at Benchmark, their .338 barrels are outstanding.

They are in Arlington WA

So im thinking about taking  my Rem 700 PSS in 300 RUM and turnning it into a 30-378 wby, what all is needed to do so it will be my first bolt gun build.

I know barrel, and bolt but is that all thats needed?

Go easy on me here guys

Or maybe even a 7mm wby or 270 wby id consider turnning it into

You can address the larger case head in two different ways. 

1) You can have your current bolt face opened up to accommodate the larger case head of the big Weatherby but you'll also need to replace the extractor when you do.  I'd highly recommend using a pinned style extractor if you go this route.

2) Buy a whole new bolt from someone like PT&G with the appropriate size bolt face and already cut for a new pinned type extractor.

Unless you are just dead set on going the 30-378 route or you'll need factory ammo, I'd do a 30-338 Lapua Improved instead of the 30-378 Bee.

I've got a 300AX (Allen Express), aka 30-338 Lapua Improved, built on a Rem 700 by Kirby Allen.  With either, you want at least a 28in tube and I wouldn't go with anything smaller than a Sendero size barrel contour.  My 300AX has a Lilja #6 1-10tw 28in barrel and I shoot the Berger 230 Hybrid Tactical 3250 fps and have yet to through away a piece of brass with this load.

The 378 case is longer and has more case capacity than the improved 338 Lapua case but when both are loaded to a usable COAL the case capacities become much more even and Lapua brass speaks for itself with regard to quality and durability.

Regardless of which big 30 cal you choose, I'd have the extended mag box installed and if you do the 30-378 I'd make sure the reamer didn't have Weatherby freebore.

So all ill need to get is a new barrel and some dies to get going  :tup:

OK I'll give them a call and what length are you having the most luck with? 30" or a little shorter?

If your going to be building a "Heavy" what's the difference between 26" and 30" weight wise? Not much? 30" just gives you max velocity within reason.

If it were a sporter weight, I would opt for 26".

Post by: b23 on January 05, 2016, 02:00:07 PM
FWIW, if you want something that is a bit of a hot rod, do not buy the Accumark in 30-378 or 338-378.  The barrel on both is the weak link, it's not only to short but is also to light weight to see any real performance out of either of these two cartridges.  I had one, a 338-378, and whenever you try to throttle them up, the groups opened up and the more you try and stand on the gas the worse they get. 

It really sucks to have all that case capacity, like the 378 has, but you have to shoot it at speeds the same as a 338 RUM or you get groups that look like a shotgun pattern.

If you hang a Sendero size contour of at least 28 inches, not including brake, with a match grade chamber from one of the many top tier barrel companies, Benchmark would certainly be a good choice, and you have a whole different animal but in the factory barreled rifles like the Accumark, not so much.

Post by: b23 on January 05, 2016, 02:11:07 PM
The 338 Edge is always a good choice and it'll save you some money by not having to mess with the bolt face issue but make sure you have an extended mag box put in it and if you don't, there's not much point doing an a 338 Edge over a 338 Rum and same deal with the barrel, I wouldn't go smaller than a Sendero contour and I wouldn't go shorter than 28in. not including the brake.

The big 30's are fun and have a lot to offer if they're built right and the recoil of the 30cal 230's is less than the .338 300's but have a good quality baffle brake installed and it's all good. :tup:

I agree after having shot the .338 Edge, there's isn't much of a difference between it and the .338 RUM. Heck the .338 RUM has more horse power than the .338 Lapua with the acception of the heaviest bullets (300gr).

A game animal or a target turret at distance won't be able to really tell the difference. Also since the .338 RUM is a slightly shorter case. It solves some of the COAL issues with the heavies in the .338 Edge when it comes to mag box length issues. My Edge has a wyattes extended mag box.

Post by: b23 on January 05, 2016, 02:36:05 PM
True, not a great deal of difference but I still go 338 Edge with extended mag box over 338 RUM because I never see 338 RUM brass for sale.  I'm sure it's out there somewhere and 300 RUM brass isn't overly plentiful but I see it once in awhile versus never for the 338 RUM and you can get 300 RUM Bertram brass from Shawn at Defensive Edge when he has it available.

man I wish I had the capitol for such a project. What kind of barrel life comparison for 300 ultra and the other mentioned projects? .338 Edge sounds like it would be nice for reaching those coyotes 800 + yards out there

Financially would be my best bet....Closest thing I can get to the .338 edge?

yes, hit and miss. Owned both, and guess I was fortunate. Both were very accurate shooters! Others though not so good. And love the Edge. Have owned and or shot dozens of them, back before most had even heard of the round. Inherently accurate when built by Rbros, Carlock, or Benchmark. But the Weatherby outclassed it in an accurate Accumark if you get a good one! :tup:

man I wish I had the capitol for such a project. What kind of barrel life comparison for 300 ultra and the other mentioned projects? .338 Edge sounds like it would be nice for reaching those coyotes 800 + yards out there

Financially would be my best bet....Closest thing I can get to the .338 edge?

As far as barrel life IDK i have about 300 ish rounds threw mine and shes atill holding great groups, id think its about the same as all the other magnums around 800 to 1000 depending  :dunno: not 100% though

:tup: You won't be disappointed! He built my first one! Broughton barrel
Defiance action
Manners stock
Jewel trigger
DE brake
Extended mag
Seekins 20 rail a integral lug mortise

Full customs builds guarantee a level of accuracy often not found on semi-custom jobs. At least  that has been my experience with having many of both. This particular build from Travis keeps 300gr. SMK' s or OTM's in a tight, should I day very tight cloverleaf at 300 yards! 100Yards? Rarely waste the time, but when it is shot at that range, one single hole. Give Travis a call. And there are many on this site shooting his rifles, hunters and competitors both!

Whoever you choose to build it, stay with a Benchmark barrel. Their .338 barrels are well known for their accuracy.

Shop around and do the math any gunsmiths name that's worth repeating on the Internet can true a action, chamber, thread and crown a barrel.

It can be tossed in most any chassis or stock of your choosing. I prefer to send my smiths all of the parts. Barrel, action, stock, brake etc.

Then I know exactly where I'm at $$$$! Wise for his work. Numbers get real inflated often when you just send a action and leave it to a smith.

When you have had enough rifles built. $3500 for a Remington 700 based custom in a McMillan tactical is out of the ball park. Some of us actually know how long it takes to do the metal work.

Benchmark has supplied the 30" barrel, trued my action, chambered(.338 Edge) threaded, fitted , bead blasted and installed a muscle brake and returned it to me for $900.00. Add the cost of the stock and bedding and look where your at NO where near $3000.00 plus. If a guy wants a name on his rifle for that money it should have " GA PRECISION " stamped on it. GA's at the top of the hill and resale is top notch and the owner has proved himself as a "World Class shooter".

The customer supplying parts will typically save a guy a little money as long as everything fits together.  This way you aren't paying the excise tax that we have to charge.  Make sure you work with your builder to ensure everything fits together.  You might have a design that doesn't really fit together and will cause you headaches in the long run.  Lots of "world class shooters" are builders out there.  Many to choose from.

Any of the top barrel manufacturers 338 barrels will shoot lights out.  I haven't had a Broughton 338 barrel that hasn't shot in the 3/8" or less range.

Both targets are 5 shot groups.  One from a customer and another from my personal rifle.

There are two different sides to builds, the well informed and the not so well informed. I tell my smiths what I want and they do it, that's what their paid for. Simple as that. Now there are others that are not so well informed, first builds or beginners. That's where a good smith can lay it out for them. Any how, I would suggest someone looking to have a custom build for the first time talk with guys who have been there and done that before tossing themselves and their wallets into the shark pool.

I'm in agreement that Benchmark makes a great barrel but just about any of the top tier barrel companies make an equally "good" barrel as well.  Hart is my personal favorite but I have some Lilja's and a Broughton that are just as good.  There are 5-10 different barrel companies I'd use with complete confidence and the same can be said about gunsmiths as there are MANY that can do equally good work.  If I lived on the wet side of the Mtns I would have no concern using RBros or talking to Benchmark about doing my work.  I'm fortunate enough to have Shawn Carlock w/Defensive Edge just across the fence 20min. away over in Idaho but I've also had Kevin Cram (Montour County Rifle) in PA. build me stuff as well as Randy Melvin (Bull Mtn Rifle Company) in Billings MT. all were excellent!  If having your build say GA Prec. on the side is important to you, then that's exactly who you should have build it but just because one rifle says GA Prec and another doesn't, certainly doesn't mean the GA Prec. built one is any better than one built by a number of other excellent smiths.  If I was concerned about having "the best" maybe I'd get a rifle from Lazzeroni because John claims his are "THE BEST"! lol

I think picking the right barrel contour for the application you plan to use it, is one of the most overlooked aspects of a build with parts and pieces pre-purchased by the owner.  When you start slinging heavy bullets out of large capacity cases you want a barrel with a sizable diameter and the longer you go the bigger you should consider.  In something like a 338 Edge that'll be pumping 300 grainers out the end, it's overall weight should be a ways down on the priority list.  By the time you get it scoped up with a quality scope that's capable of consistently dialing up and down with repeatable results, you'll be around 12-14lbs and possibly more, depending on the stock you choose.  Take a look at the barrels in the pics of these long range shooters, they generally have pretty good sized contours on them, at least the ones that shoot really well typically do.

I like Benchmarks "Sendero" contour fluted. I've had rifles built with their lighter and heavier contours. The fluted Sendero was well balanced for weight and accuracy and of course a 30" barrel on my Edge.

Not a lot of difference side by side. And yes, the 338 Edge is the most efficient...
L-R.. 30/378 Wthrby, 300 RUM, 338/378 Wthrby, 338 Edge.

Your gains are to be had on the bullet selection of the 338 by going to the Edge getting into Long Heavy Balistically superior bullets vs. what is available in the 300.  300 RUM can push some big ones that are in the 225-250 grain range.  I don't know all the options, but the 338 gets into the 300 grain bullet range, which is where your gains are to be had for what most are pursuing.

If you were going to keep both 300 RUM, I would set one up to shoot light and fast.  168-180 grain and then set up the other to shoot heavy longer choices in the 225 range.

If I already had an ultra mag action, I'd go with an Edge. 

I just started a new build from scratch and the edge was at the top of my list.  If I would have had the appropriate action laying around, it would have been a no brainer.

I still wouldn't rule out a 30-338 Lapua Improved or 338 Lapua Improved.  Both have a pretty decent size fps advantage over the 300 RUM or 300 RUM based Edge and 338 Lapua brass is much easier to find as well as last significantly longer.

These 2 are in a world of their own and really would need a custom action to get the most benefit out of them.  Might be more than he wants to bite off at this time.

The customer supplying parts will typically save a guy a little money as long as everything fits together.  This way you aren't paying the excise tax that we have to charge.  Make sure you work with your builder to ensure everything fits together.  You might have a design that doesn't really fit together and will cause you headaches in the long run.  Lots of "world class shooters" are builders out there.  Many to choose from.

Any of the top barrel manufacturers 338 barrels will shoot lights out.  I haven't had a Broughton 338 barrel that hasn't shot in the 3/8" or less range.

Both targets are 5 shot groups.  One from a customer and another from my personal rifle.

Little left and a little high ;)
3 shot "groups" are one thing..5 shots single hole, another. Combine an very accurate built rifle, and someone who can shoot it, This is the result! Nice shooting Travis! :tup:

The top target is actually a 3 shot group.  My buddy shot it over the summer.

Hmmmmmmm.

I sense your normal sceptisism, so since I own one of the rifles anyone is more than welcome to shoot it.    It has shot many groups in the .1's and under as well as many sub .25 moa groups at distance with both experienced and new shooters.

I got in the habit of only keeping the exceptional ones. It better be well under .2" if it wants to come home with me!

I wouldn't rule out the 7 RUM with the new 195 Bergers at about 3000fps. It should give both the 338 Edge and the 300 RUM a run for their money at most reasonable ranges. Not to mention that in identical configurations the 7 RUM will have less recoil, and it's pretty noticeable after a day of shooting. It was much easier for me to spot hits when I had the 7 RUM barrel on my gun shooting the 200gr Wildcat bullets @ 2980 fps than it was shooting the same gun with the 338 Edge barrel and 300gr Bergers @2925fps. I'm not afraid of recoil, but I don't see any need to get kicked around if it's not necessary.

You know, being internet cool is the first step to being internet famous. The next step is to make tutorial videos and display how your superficial knowledge of a subject provides you with just enough insight to convince up and coming internet cool kids that you know what you're doing.

I'm not going to lie, I consider myself a bit of an expert on this whole "internets" thing. I was offered a youtube sponsorship by a toothpaste company out of Azerbaijan that I've never heard of. Yeah, I'm kind of a big deal.... :chuckle:

just feed that rum some 230 bergers and call it good. then when you build a custom I think you would want a bigger gap than just going to a 338 edge, think cheytac! sounds like you have time to think about it, who knows what you will come up with.
