I ended up acquiring some 200s and tried them in my Accumark .300 WM. Tried the Australian equivalent of H1000 and had nothing but dramas trying to achieve accuracy. Best I could manage was just over 1 MOA at 100 meters (110 yards).
Switched to RL22 and presto. Bad groups hover at 1 inch. My chosen load consistently prints between .4-.6 MOA. Going to skim bed the ally bedding block and see if things improve. Seated 20" off the lands.
