30-378 Weatherby ?

[Coasthunterjay]

So this is a power house of a bullet...so anything bigger than elk of course this would be awesome...and yes i understand bullets are expensive...ill reload if i make this step....

But what about deer? say 100yards?

most the deer i shoot are at 250-300 yrds plus, but a few have been around 100yrds....

would this Gun be to much for deer. sure no it would put them in there place....lol....kind of interested....

it's the caliber that guy eastman shoots everything with for what it's worth. it's a 30 caliber bullet with a whole lot of juice behind it.

OUCH!!!!!!

I thought you wanted a gunt that didn't kick so much? 

I think if you use a good tough bullet you won't lose too much meat on a deer at that close of a shot. But I would not use light bullets like nosler ballistic tips, spire point, ect...

Put a barnes X bullet or Nosler partition down it.

Lots of gun for a 175# animal
I have never loast a deer with my 243, Very little blood shot too

I have shot three muleys with my 30-378 (180 gr barnes) there is less damage with it than with my 257 Roberts or 7mm . as far as recoil goes it kicks like a 270, but it is VERY LOUD  it is a great gun but the cost is very steep, I would look at the 300 R.U.M  to keep the cost down.

do you know anyone that shoots the .300 RUM or .30-378 Weatherby?  If you do, I would see if you can't go out with them and spend some time shooting a half box of shells, just to see if the recoil is something you can stand. 

The old .300 RUM's kicked like a mule, because the synthetic stocks weren't the quality they are today, and the recoil pads weren't near as nice as they are now.  I spent about 20 rounds with a buddy of mine to make sure that I did in fact want and Ultra Mag.  My wife got me one an XCR for my birthday in December, and I am waiting for backordered brass to start loading, so I haven't gotten to shoot it yet.  My scope just arrived a couple of weeks ago and got that mounted last week.  It looks pretty, but it hasn't had a single round shot through it yet.

I did look at the .30-378 Weatherby and shot it.  The Weatherby is heavier and more importantly seems more weight forward heavy (barrel heavy) to me.  And I like all of the weight to be back in the Action and further back.  Seems easier to hold on a target off hand if the weight is back.  It might just be me, but it is what I like.  Barrel weight is one of the reasons I have considered the Christensen Arms and few other brand's carbon barrels - they lose 1/2 pound or more and most of it comes from the barrel.  But it is a very expensive 1/2 pound.  Just my thoughts on the subject.

whoever buys the 30-378, I can make you a good deal on brass.

[Coasthunterjay]

Yes i have shot several 300Win Mags and RUM's.....ALOT.....never shot the 30-378.......

I have several friends with both...probably a half dozen plus and i usually actually am the one they call every year when they need help sighting in there rifles because its to much gun for them. But i have shot alot of guns and now i can take it...

if i got any it would have a break, but most that i have shot didnt have one...

But just wondering...not that i could afford one, just interested in the caliber....

Anyone know ballistics on the 180grain accubonds or barnes through it ? ? ?

[whacker1]

No, but I will know soon for the RUM.  Many of the folks I know have difficulty getting the bonded bullets to shoot at this speed.  They ended up shooting the match grade bullets to keep the patterns tight. 

I can't believe that I have been waiting over 60 days for back ordered Nosler brass.

who shoots this gun and loves it?

[WDFW-SUX]

I've owned one......To expensive to shoot IMO $120 a box for factory and hand loads use about 118 grains of powder per shell.

Its like throwing a 5$ bill down range every time you pull the trigger.

Recoil is not an issue because they come with a factory installed break on all the accumarks.

Dang!!!!  118 Grains of powder?  You  must have been using the 5010 or 50BMG powder.

Anyone have powder recomendations or worked up loads that worked well in this gun?

The .30-378 Weatherby Magnum

By Chuck Hawks



In recent years there has been a trend among wildcat cartridge aficionados toward outsized "super" .300 magnums. In 1996 Weatherby responded to this trend by chambering their Mark V rifle for the huge .30-378 Belted Magnum.

Weatherby factory ballistics for the .30-378 call for a 165 grain bullet (SD .248) at a MV of 3500 fps with ME of 4488 ft. lbs., a 180 grain bullet (SD .271) at a MV of 3,420 fps with ME of 4676 ft. lbs., and a 200 grain bullet (SD .301) at a MV of 3,160 fps with ME of 4434 ft. lbs. Weatherby ballistics tables show the following trajectory for the 180 grain Nosler Ballistic Tip bullet: +2.5" at 100 yards, +3.1" at 200 yards, 0 at 300 yards, and -7.5" at 400 yards.

Hodgdon Powder Company reloading data shows that a 180 grain Speer boat-tail spitzer bullet can be driven at a velocity of 3213 fps by 105.0 grains of H870 powder, and to a MV of 3412 fps by 111.0 grains of H1000. The 200 grain Barnes X-Bullet tested by Hodgdon could be driven to a MV of 3105 fps by 113.0 grains of H870 powder, and to 3206 fps by 116.0 grains of H870.

Last but certainly not least, the 220 grain Nosler Partition bullet could be driven to a MV of 3098 fps by 113.0 grains of H870 powder, and a MV of 3180 fps by 116.0 grains of H870. With a well placed bullet this should do for any animal on earth, although no .30 caliber cartridge it really the best choice for heavy, dangerous game. These velocities were all achieved in a 26" barrel and used Weatherby brass and Federal 215M primers.
