338 Win Mag help

I'm trying to get my 338 ready for some shooting. I have 50 pieces of new Remington brass, 100 Hornady 225grain SST, Federal 215 primers, and assorted powders including RL19. I've loaded for years but never for the 338 Win so I'm looking for some pet loads or a good starting place. Im shooting a 26 inch barreled Savage 116 with muzzle break. I'd like to push em around 2800 fps I think.

Thanks Much

Also thought I would mention that I am hunting Alaska game. I want one round to hunt everything. I plan to use it on Moose on down to Goat and Sheep. I might even use it for Grizzly if I get the chance.

You will find RE19 to be the best powder for your 338!

My pet load for the 225gr Nosler BT bullets is 76gr's of RE19, Fed 215 primer in Rem brass, this load gives me 2890fps in my 26" barreled Win Mod70.
The Speer max load for this is 78gr's, which was safe in my rifle, but 76gr's gave the best accuracy, 5 shots into a ragged hole @ 100yrds.

The trajectory of this load is awesome and, I bet your SST's will have a very similar trajectory. 3" high @ 100yrds will give you a 8" MPBR of 330yrds, near enough, and should be zeroed at 280yrds and good for all the game you mentioned.

My hornady manual says 73.3 grains is danger close with the 225 grain SST. Is there that much difference between a 225 grain SST and the Noslers that allow you to use so much more powder.

I have seen so many variations in max loads that I take every recent manuals info with a large grain of salt!

I work up to max in MY RIFLE. I will load to the max taken in several manuals, if it's 5gr's more as in this case, I carefully work up to max closely watching for any pressure signs, excessively flattened primers, ejector marks, primer cratering and hard bolt lift. I had none of these signs with this load and a few 225gr bullets.

I have also noticed that a lot of data for the 338 does not approach a compressed powder charge, why this is I'm not sure, but I have had very uniform velocities and pressures with compressed loads in this calibre, moreso than non compressed loads.

You can only try it carefully in your rifle and see how it pans out, it was perfectly safe in my rifle, and obviously in the Speer test barrel!

Re: 338 Win Mag help

I would suggest a different bullet, it's been my experience that the SST in .338 is to fragile for anything bigger than deer, even at ranges over 400yds. They tend to "explode" on elk and buffalo. The 225 Hornady spire point shoot's almost as well (accurate) as the SST but will hold up MUCH better. As far as powder, just test 'em until you find the best for your rifle.
