Loaded per Berger instructions to find the sweet spot, and the best group was 1.5" at 100 yards.

OAL = 3.455, Velocity Avg 2,861 FPS, ES = 25 FPS 2.1" group

OAL = 3.495, Vel Avg 2,886 FPS, ES = 17 FPS 1.5" group

OAL = 3.535, Vel Avg = 2.868 FPS, ES = 27 FPS, 1.5" group

So I'm wondering, should I try a quicker powder? Something like 66.5 grains of H4350?

The rest was rock solid, and the rifle is a great shooter with 180 grain loads.

What am I missing?


I tried to help you out with this before but you listened to others and paid no attention to my post obviously. will try 1 more time
RL22 works great with 165gr-180gr bullets as does Ramshot Magnum but with the Berger 210gr VLD I tried many powders in several different rifles of 300WM chambering and THE powder for this combo is H1000.

btw try H4350 if you must, but you will find the SD so high that even if it shoots good at 100 yards you wont hit much beyond 600yds.(defeats the purpose of using a high B.C.bullet)
