I was finally able to work up a load for the AB in a 300wm. The final load was 67.0 H4350, WW cases, Fed 215 match. All 3 shot groups were 0.75in to 0.9in at 100yds. Velocities averaged 2952fps out of a 26in barrel.
Every time I tried to push the AB faster (with RL-22 or any other powder) my groups opened up to 1.25in to 1.5in. Has anyone else experienced this?
