I just picked up my friends new accuracy international psr And he wants me to find a good load for .308, 300 Winchester Magnum and 338 Lapua Magnum. Anybody shooting one of these particular rifles I would greatly appreciate load data thank you. AS
You are now in a position to actually use an awesome piece of equipment, and your trying to "cheat" by having others come up of load data?
Make a load, and see if it works. Try something else if it doesn't live up to your expectations, or if you think you can do better.

Looks great those are very nice for sure, got to handle one just last week! Have fun developing the loads as I know I would for sure. Best of luck to your friends Mom. Been shooting 338LM for 3ys now and it's a great cartridge. I know that Frank mentioned the 285 Hornady's, haven't tried them yet but it's on my list to try as they were the best performers in all makes and twist in the 338LM shoot out @ Gunsite. Here are some of my loads from my 26" 1:9 twist
300gr Scenars & Berger Hybrids .015" from the Lands 2760fps FGMM mag primers
90.5gr Retumbo & 88gr H1000 & 93gr N570
250gr SMK's & Berger Hybrids .015" from the lands 2960fps FGMM mag primers
88.4gr N560 & 88gr H1000 & 88.4gr H4831SC
Starting over now since I installed a 30" 1:9.3 Chanlynn barrel and my first loads were allitle hot 2965fps 300gr Scenars 92.5gr Retumbo had stiff bolt lift.
Have fun with the load development and let us know how you fare.

I have a the AI PSR and up to now have been shooting Federal GMM ammo. I did my first reloads tonight. they are (these are just a start) 82.01 grains of Retumbo with 190 SMK and 78.0 H1000 190 SMK. I am trying to get close to factory GMM as I can. will go try them out in the am. I am getting 3145FPS AVG from the factory stuff. I hope one of these loads is close.
