Title: 1000 Yard 338 - I Like Big Guns Part 2
Post by: luvmystang67 on March 21, 2024, 02:18:05 PM
Okay, so based on the "I like big guns and I cannot lie" thread, I've decided I need a big long range 338.  I'm going to shoot big heavy bullets really far, because... I want to.  Think 270-300 grain 338 shots at 800-1000 yards.

So now here comes the debate with no definitive answer, but looking for thoughts and opinions based on some of what I'm considering.  I'm thinking of long range hunting for elk as a primary application, alongside just long range shooting for fun, but its got to be somewhat packable.

1) Not considering a 338WM.  I've got a 300WM and a 375H&H, I don't need a 338WM and probably don't need another gun generally, but humor me below.

2) I could buy a 338 Lapua or a 338-378 Wby.  I'd be handloading primarily.  I'm a little of the mind, if you're going to buy a factory rifle and handload, why not buy the bigger badder one, which leans me towards a 338-378.  Brass seems to be the only compelling reason to look at a 338 Lapua instead.  Am I missing something else?  I'm assuming recoil perhaps, but with a brake, I think we're kind of same-same here.

3) If I went build... I think the 338 Norma looks kind of neat.  I know, brass isn't as good as the lapua brass, but handloading extra long bullets with "not incredibly long barrels" seems to be kind of this caliber's niche.  I'm thinking I can build what is effectively of a 338 Lapua hunting repeater, in a smaller size, with similar performance.  But I'm also kind of cheap, so I was trying to figure out if I could find an action from a donor rifle and get a rebarrel in 338 Norma... best idea seems to be a MarkV Weatherby donor, but nobody in north Idaho seems to want to work on a weatherby action (that I have found yet).

4) I go back in forth between "ah heck, just buy the $1600 338-378 from Buds and start shooting" and "wouldn't it be cool if I picked up a donor MarkV action and had a 338 norma barrel thrown on there".

Thoughts?

1. Why not use your 300 win mag for long range shooting and hunting? There are plenty of viable bullets for just that.

2. What do you think you would gain in performance with the 338-378 over a lapua or your 300 for that matter? And how much real impact will that have on your shooting/hunting?

3. What exactly is the difference in brass from 338 norma and 338 lapua that makes you think 338 lapua brass is better? Lapua makes brass for both, as well as 300 win mag FWIW. Neither works inherently better in shorter or longer barrels.

4. How much shooting have you actually done at long ranges? How much do you intend to? Long range hunting takes lots of practice. Weatherby rifles are ergonomic abominations at best, there are much better choices for shootability at long range. If you are thinking of building a rifle why not put money into the 300 win you already have? What would a 338 do that it cant?

This whole post reminds me of a day at the range when a guy had a 50 bmg thinking that was what he needed to shoot 1000 yards. He shot round after round after round never hitting even a plate at 880 yards. Then he was flabbergasted that my 6mm could hit them consistently. Horsepower is not a replacement for shootability or practice.

Also for the record, i have shot large 338s just enough to realize i dont like them. And dot want one.  :chuckle:

I think all those are overkill unless you plan on stretching it way past 800-1000 yards  :chuckle: that being said, I’m all for silly reasons to play with new guns so have at it  :tup:

I used to load a Weatherby 30-378 and his 375 H&H for a friend of mine.
His 100 yard group was 5" the first 5 shots he put through the 30-378 with factory ammo. He said the gun was "not accurate".
I (and his friend that was with us) watched him flinch from the first shot.
His buddy sat down and shot a 1" group with 5 shots and declined to shoot it any more because it kicked so hard.
I am not sure if the owner ever got to where he could control the 'flinch', as I do not recall going to the range with him after that, but he did always talk about it being a 1000 yard gun. I have sold more than one gun because of the recoil and it causing me to flinch with other lighter rounds.

I hope, before you make any 1000 yard shots on critters, or even 500 yard shots for that matter, that you test out your abilities at a capable range.
I believe Tacoma sportsman and Paul Bunyan both have a long range meet once a month.
Best of luck on your choice of weapon!

To answer a few questions...

1) My 300WM is a 1/12 twist, hardly ideal for larger bullets that are often desired for longer range shooting, 180 grain is about max and even then probably a bit heavier than ideal.  Can it shoot 1000? Sure.  Should I put a 180 grain bullet from my 300WM on an elk at 1000... starting to get iffy there.

2) Will I practice, or have I?  I've practiced at 5-600 yards yes, but most of my guns aren't quite set up for this and also aren't necessarily as accurate as I'd like to begin with.  I've taken elk at 500 with a .30-06 with an old 3-9x scope and it took a lot of poorly penetrating bullets to get it down.  How on earth am I going to practice at longer range without a setup equipped to do it?  And yes, I'm not going to go sight in a 338 lapua at 100 yards and then try to smack an elk at 1000... I'm not a jerk, I promise, and only a jerk would do that.

3) I don't mind getting whalloped by recoil, a sick part of me enjoys it.  Maybe I'm making up for being recoil shy as a child and thinking dads .30-06 was the baddest gun in the land.

4) I also just want to, this is going to happen in some capacity, it is really just which one.

I built a 338 lapua. I started out with a Stiller action, then I had Ron Smith build me a gain twist barrel for it. If I remember right it was 22 1/2 -11. I don't remember the bottom metal but I had it all stuck into a Manners stock. I did have a six to 24 scope mounted on top. It was a heavy rifle even though I turned the barrel down to a medium weight. I shot 250 grand Sierra game kings out of it because that's what I shoot out of my 338 win mags and I like how that bullet kills. I never took it past 600 yards. And I never did kill any game with it it was a fun rifle but I needed a roof on my house so I decided it had to go. I still shoot 338 win mags and have shot mule deer out to 527 yards but I don't make a habit of it I prefer hunting.

I think what he’s saying is for you to take the 300 that you have and build a rifle out of it. Maybe not. What do you mean by 180 grains being about max? Do you mean for the 12 twist barrel?

:yeah:
Put some 180-190 bergers in that 300 and see what it can do. At the speed you can shoot them 1000 will not be an issue at least for targets. And likely terminal velocity for bullet upset depending on environmentals.

I was in the same boat a few years back.  I ended up with a 338 lapua and this is why....?? (not saying there aren't multiple answers, just what made it easy for me.)

1.  Brass is readily available.  Quality brass is readily available. 
2.  Factory rifles are readily available....and there is a lot to choose from.   
3.  Price was not going to brake the bank, just incase I didn't like it or didn't shoot it much.  Figured I could get my money back out of it if I wanted out a couple years later.  If you go custom, you will never recoup your money if you decide you don't like it.  I figured if I ended up liking it....I could go custom at a later date. 
4.  It is just fun saying you own a lapua... :chuckle:

I ended up with a Savage 110 FCP, which sits in a HS precision stock.  It is a heavier rifle, but manageable and is easy to shoot with a brake.  The savage action also allows me to do a barrel swap without the need of a gunsmith.  Figured the action would make a good custom build at a later date should I want to. 

I am pushing 260 Hammer Hunter at 2950 fps and it will consistently shoot sub 1" at 300 yards.  It is a sub half MOA rifle all day long. 

Now...other calibers I looked at but decided against. 

338 rum....brass is almost impossible to find.  Not that many quality choices for brass either.  Price is the same or more expensive than 338 lapua brass. 

338-378....Same reasons as the 338 rum. 


All the above being said.....If you haven't shot past 600 yards, I'm not sure you can really appreciate how hard it is to read the wind at 600+ yards.  Point being....you should be shooting a ton and in different weather conditions before you ever think of shooting at game at those distances.  Also...you should never assume your ballistics calculator is accurate at those ranges....verify, verify, verify....and make corrections to your calculator as necessary.  600 yards is easy.....700 yards is very doable....beyond 700 becomes very difficult if there is any wind at all.  The difference between a kill and a gut shot. 

My next rifle will be a 338 rum or 338 lapua that I push 175 grain Hammer Hunters out of.  I will be a speedster.

Throw a new barrel on that 300 winnie and there’s your 1000 yard gun! Plus your burning almost half the amount of powder as the 338-378 :twocents:

You are right on target with your thinking! I have 338-378, 338 Lapua, 338 Lapua AI, and 338 WM w 215 bergers.

At 1000 yards funny things happen.  If I ever lost an animal at that range with a 300 gr Berger I would know its my fault.  With anything less you are going to be wishing you had gone bigger.

My son and buddy have older factory 338-378’s I bedded and dialed in reloads that are as accurate or slightly more so than my lapuas even.  But those bottlenecks are finicky to match to dies.  My son’s only shoots virgin brass best.  You may have to bump back .006 or more to chamber depending on die.  Speed will not be faster than a standard Lapua ( 2850 -2880 is a sweet spot for both with rl33).

But if going to the Lapua at 2850 perhaps you consider the Lapua AI getting you to 3000 ?  You don’t have to trim brass and can always down load and may find a fast load with dependable H1000 at 2900+ where the lapua is 2800 with it.
With n570 you will be around 2970-3000 .

What version of Lapua AI ? If you go down that rabbit hole see your neighbor in Rathdrum at defensive edge and chamber a 338 Terminator - his version of Lapua AI.    I sent my Lapua Ai to him yesterday to be rebarrelled.  Replacing 30” carbon with 26” fluted Hart sendero contour which in terminator chambering will still hit 3000 fps with 26” barrel.   Brake is titanium 1.2” from Salmon River Solutions N Idaho.   

But the 338 Norma is a fine chambering, with n570 and a long seated bullet and 30” barrel you will be hitting 2850 also.  Your neighbor HCA chambers a fine one.    Hope this helps!

If the 338 Lapua Improved interests you I have a brand new one built on a BAT HRPIC action McMillan A5-adj stock Jewel Trigger Lilja barrel for sale.  Mine is the 40° shoulder version that is throated long for the 300's.  I have Redding Custom dies that'll go with it too.

Have you considered a 338 edge. I built one off a rem 700 action. It shoots 285 grain eldm's at 2850. It shoots incredible. 93 grains of h1000.

Take your existing rifle, screw a quality barrel in .338 Edge. Add quality scope and trigger, grab some dies and some .300 Ultra brass, add some H1000 and 300 GR. Matchkings or Bergers, and shoot👍

Thought I might have a lead for you on a gunsmith who would work on a weatherby markV action.  Contacted him and he said that he did not work on them as the cost of tooling needed to work on them did not justify the demand.

Part of the problem with using MkV actions, particularly with long high BC .338 bullets, is if you want to use it as a repeater you're very limited on the max allowable cartridge length.  It's been awhile since I had my 338-378 but if I recall around 3.750 was all you could get in their magazine and I'm not sure there's anyone that offers an extended mag box for them like they do the Rem700 or 700 clones.  It's not like that big Weatherby case is lacking capacity but the, only, reason I'd ever build a 338-378 would be because it has the biggest case of any production .338 cartridge out there so I certainly wouldn't de-nut it by limiting the OAL to 3.750

The 338-378 is a big long case and you stuff a long 300gr bullet in there seated to 3.750 it kind of neuters the capacity of that big ole 378 case.  Not that you need to run one of these things as a repeater especially if you're using it for LR or ELR work but I wouldn't spend any money on a repeater type action to have to use it as a single shot.

My Wby Accumark 338-378 shot decent-ish but only if it was throttled back which made it kind of a turd in the velocity department.  As soon as I got much past about a mid level load with the variety of different powders I tried it would start scattering shots all over the paper.

The Wbee 338-378 mag holds up to 3.800.  The bullet is buried in the powder column but will still hold about the same as a LapuaAI - 113 gr RL33. Never tried single shot as it seemed kind of silly to have to pull the bolt to unload, but I guess if you pick up 100 fps maybe worth it……

Well, picked up a .338-378 used at the show yesterday. Can’t wait to practice a few times and then take it out for elk at 1000.

Just kidding

But pretty excited. Now I need to spend 2x the rifle to get it glassed and fed. Looks to be an older mark v and too lightweight for my own good.

Well, I feel like its worth making an update here, mostly because I'm excited.

Was finally able to source some nice magnum primers.  Got some Rem 9 1/2M, some CCI 250s and some Fed 215Ms.  Found some new Norma brass for a somewhat affordable $2/piece.  Picked up some 338 ELDM 285gr, 280gr Barnes LRX, 300gr SMK.  Played around with VV N570, H1000 and Retumbo.  Finally got around to putting it all together with the Trijicon Tenmile that I picked up here on the forum (thanks @cjc23), and went out shooting yesterday.  I'm able to get 2900 FPS with the 300gr SMK and 2960 with the 285gr ELDM, and 3020 with the 280gr Barnes LRX.

The best results (using ladder loads, so variant velocities) were with the H1000, Rem 9 1/2Ms and the 285gr ELDM.  Those shot about 1" 5-shot group, even at different velocities.  The VV N570 provided the best velocities with the 300gr SMKs with no pressure signs up to 105.5gr and 2912 FPS.  The Retumbo was a little more sticky on the bolt for the same velocity as the VV N570.

I'm pretty excited about this rifle, especially the H1000 results.  With the ELDM bullets at 2960fps, it generates >5,000 ft-lbs at 100 yards, ~4000 ft-lbs at 400 yards, at 1000 yards it still has 2365 ft-lbs of energy.   Drop at 500 yards is only 34" (with 200 yard zero).  There's no reason this shouldn't be able to kill any animal in North America at 1000 yards. 

Compared to my .375 H&H shooting a 270 grain Barnes TSX FB at 2700 FPS: the energy and velocity of the 375 at 300 yards is roughly equivalent to the 338-378 at 1000. 

Does my shoulder hurt? Yeah, a little.  But its the pain of optimism and excitement.  Now I just have to drill into a winning load and practice, practice, practice.

Sidenote: I did want to glass bed it, but my cheap plastic stock that came with it will absolutely not work for that.  I was going to buy a new (used) one to bed, and found some pretty good deals at Numrich Gun Parts... instead of buying a used Bell & Carson synthetic stock for $150, I went for a brand new $200 factory weatherby walnut stock... I too have some eye for beauty and couldnt resist.  I still have some work to do on it for fit-up as it was meant for a slightly different profile barrel option, but its going to look great.

Sidenote 2: I forgot the tiny allen wrench for the zero stop and I put a 20MOA rail on it, so I had to aim at a target 20MOA below my actual target, which made evaluation of accuracy a little difficult.  Will post more when I know more.
