Re: .338 Win Mag loads

I have a Rem.700LH that I bought new to build a 7stw out of it, but my gunsmithtpld me to try it put first that it would probably shoot and boy was he right. It shot the first load I ever tried in it and it will pretty much eat anything you put in it.
The most accurate load it shoots is 68.5gr. of IMR4350 with a 225gr. Hornady SP- 3 shots made one ragged hole at 100yds. And will plant anything it hits and they other load is 74.5gr. of IMR4831 with a 200gr. Nosler BT and plants things also.
I do want to try the 185gr. ttsx to see if they shoot as well. This is a powerful performing, hard hitting rifle and I don't plan on touching it other than to hunt with it and don't see any need for anything bigger that this case unless you plan on shooting it a long way. The only thing it does that could be improved is the recoil, it will punch you pretty good with those 225gr. Loads.

Yep, .338's do recoil, but not nearly as badly as .375's, and they are MUCHHH better for long range shooting and, with heavier, tougher bullets (like the Barnes baded solid for example), will shoot just about clean through anything. Knockdown at range is also vastly superior to 7mm and 30cal mags. Personally, I consider the 338WM to be the ultimate all round african rifle. Only constraints are that you dont want to shoot anything you are intending to eat at close range, esp with a light bullet. Also would not rate it as a "charge stopper", but then I have yet to see anyone use a scoped rifle effectively in that role. Recoil can be tamed with a boss and magnum recoil pad - which make for a better long range set-up. All round, I like, i really do like.

338 Win Mag
225gr Nosler Accubond
Winchester Brass
Federal 215 magnum primers

Here is what made the monster difference
H4831 sc powder - less than 3/4" consisitent groups at 200 yards
2785 FPS MZV - 73.4 gr (remember this is for my rifle, not yours)
.033 off my lands

I loaded 60 rounds with my recipe
proven 4 times at the range at 200 yards. (3 out of 4 3 shot groups under .625.
I am saving the rest of hunting

BTW: this is a Weatherby Vanguard Serie 1 - a 489.00 rifle....

Bottom line: test with different powders and seating depths.

388winmag
.338 Win Mag barrels last just about forever. That is one of the great things about this cartridge. I would not be surprised if the barrel in that Weatherby Vanguard was just starting to get "Run in" and that is why your accuracy improved. This can take quite a while with some rifles.
Anyway that is good shooting so well done.

Re: .338 Win Mag loads

now thats the kind of group I like does the hodgedon powder do as well? Have you experienced a 225 grain load that does that well?

Incredibly,that load is the second I tried.The first was just a different bullet,hornady 250 round nose.those shot just over an inch.I bought some blem 225 gr interbonds from midwayusa that were alright.67 grs of imr 4831,good for around an inch moa.I haven`t tried h4831 only because the imr powder does so good in my rifle.
