Recently spent some time on some load development for my RPR in 338 LM and found a decent load for H1000 and Hornady 300gr A-Tips. For reference only, make sure you check the proper load data for your rifle and check for pressure signs.
Brass: 338 Lapua Magum Lapua Brand Brass
Powder: 88gr of Hodgdon H1000
Projectile: Hornady 300gr A-Tip
Case Overall Length: 3.740"
Dies: Hornady Custom Grade 338 Lapua Magnum dies
More testing is still to be done with this load as I had many other loads I tested so I couldn't load too many of these. However I managed a 0.46" 3 shot group at 100 yards. Once I have time to load more of this same load, I will be doing further testing such as 10 round groups and longer range groups.
Again, use at your own risk and check safe data info before utilizing the above data.
