7.0 GRAINS, 1.1, 1.25, 1.9, 2.075, AVG 1.581 This Striker shoots better than my 12FV in 223.
I thought bullets were pushed in the case on chambering, irregularly, affecting accuracy. I crimped the case mouth in Lee collet die, then didn't, crimping doesn't seem to affect accuracy so far.
Bullets, 225646M and 225415, are GCed, LLA, unsized, and seem to shoot fine. Maybe sizing is an extra step we don't need.
22-250 and other reported big 22s seem to shoot as well as smaller cases. Long ago I analysed CBA match data and found that the small case doesn't help accuracy much, if at all. SS rifle guys are seeing this in 32-40 vs. 30-20 or Millers. Maybe we need bigger cases. I've got a 22-250 barrel on the way, I'll screw it on a Savage rifle and see how it shoots lead. Maybe use the 10 shot group method to prove one way or the other. Why waste all that powder?
