My mission to find the best short barreled big 338!!!

You are the person "waveslayer" that stated "The Norma was built around the 300 gr bullet and shines over the Lapua past 1500 yards.
so you post your DATA!
Don't ask me for data to dispute - I am not doing the compression - You are the one making the statement!
I personally think all the "Good Design 338s are GREAT for LR Hunting.
It is just that there ae so may cartridges that are basicall the same. Just that different manufactures want to get into the game.
Look at all the Needmores!!!! They are basically the same cartridges as the needmores. It is just that Hornady and Creedmore got together and offered a 1:8 twist in a 6.5. They blew out the .260 Winchester with a 1:9 twist in rifles and then the Snowball just kept rolling. Now you have all the Needmores from 6mm, 25, 6.5 and a big following in PRS.
The .308 Winchester Case has got to be one of the "BEST & USED" cases for Hunting or Military in the 21st & 22 nd Centry.
Name me another "Better" Cartridge Case for Hunting, Target, and Military that is being Modified in different calibers to this Date in History!!!

NONE Military Big Mag
OK beside the 300 WM, 338 LM

Someone got defensive real fast. The whole bases (look it up) for the 338 Norma was to have better performance using the 300 Grain pills to outperform the 338 Lapua using the same 300 grain pills... So you are trying to prove me wrong because I stated it out shines the Lapua past 1,500 yards or meters... Prove to me it doesn't then... where's the data to say otherwise, you say you don't want to dispute but yet you are without the data you in return are asking for?... confusing yes.

.308 is great... I'd take my 7.82 Warbird over the .308 for hunting, but that's me. There are a ton of similar calibers out there, it's what grows the sport and technology. This drive has driven the sport to a whole new level and the RD coming from it is impressive. Random thought, why did Sig design the new SAW using the 338 Norma over the Lapua? That I am not sure of, Norma influencing that decision?...

I'll name the 300 Norma using the 215's if you want me to name another...
 
The norma and the lapua are basically the same .the lapua has the edge on case capacity.If they are both built to accommodate a 300 grn bullet the lapua edges it outs as doe the imp version. I have many friends with the Norma, one take 3 -5 elk a year with his rifle last ten years .Ranges to 1000. I have another two friends with LAI.One shot a 4'' 3 shot at 1 mile, the other shot a 3 target agg for a world record with his at 2000 yards 19'' group Alex W.built one of the rifles. I have 2 338 NM. The lapua is used in all kinds of countries all over the world for years now in a military capacity

Sorry not trying to prove you wrong. Can't prove a negative! Just wanted to see" Your data" stating that the 338 Norma "Out Shines" the 338LM at 1,500yds. We are always looking for better cartridges and if your real life data supports your statement maybe we should change over to the 338NM.
Thanks for your research and input. We just may change over to the 338NM. but how much of a change of ballistic would warrant a change in Dies, Brass, Reamers? Is it going to give us +50fps or maybe -50fps.????
Thanks for the conversation.

I am kind of having a hard time wrapping my head around this. Are you saying the Norma will shoot a 300 gr bullet faster than the Lapua?
 
The original,Factory type lapua was designed for 250 gr bullet.Thus 300 gr was pushed down into powder columns more.But custom builds solve that issue. Relating again to Sloan ,they took comp rifles and cut them down to I think 22'' and they still really did well, which relates to this thread.Ive had Normas since 2010.Some guys on the hide have really pushed there's to the limit.Im 100 yrds from Defiance,2 miles from Proof,30 minutes from Steve at Hammer.There are a lot of guys with 338 NM in my area also 338 LAI too

Man this thing derailed fast!

I can't wait to see your tests on these short barreled beasts and it's awesome you are using good old H1000 not unobtainioum powders.

Yeah it happens A lot. Hopefully we can get back on track guys!!

H1000 is the only powder I will use anymore in basically all my rifles.

In my opinion it is the most even keel for all cartridges to be compared to each other with!

But then again I'm not out to get a pat on the back just cuzz it will do XYZ velocity "in my rifle" or "if you had XYZ powder it would gain you 100fps blah blah blah" I dont care in the slightest ... I want consistency and accuracy first.. and If this cartridge doesn't do what i want ,, then i step up a size and try again!!

A big reason I find myself on this forum less and less. Super annoying.

I have noticed crazy things with h1k in barrel wear (or lack there of) as well. Nearly 200 rounds down my 30 nosler, and the throat looks like this

My standard .338 Norma mag I had showed significant signs of fire cracking at under 100 rounds. The 30 nosler adg brass is about 102 grains H20 capacity, and I believe Peterson .338 NM is about 107, so 5 grains more but also a larger bore, so bore/capacity ratios should be similar, if not then the Norma having more favorable ratios for bore life.

The difference? I ran N570 in my Norma. It's well known n570 burns hotter than H1000, but my observed difference in throat wear between the two is significant, if not surprising. I know barrels are wear items, and barrel life isn't a huge concern when working with large magnums, however if I can get 50% more barrel life from my fire breathing elk thumper, while keeping awesome consistency, temp stability, and loading forgiveness, with a powder I can find easier, and the only thing to give up is 50-100 fps max? Yup, I'll take it every day of the week.
