I just got back from shooting my first BP Creedmoor Match this weekend.
Now I've been shooting high power and loading match ammo for HP and 1000 yard shooting for over 30 years, I learned when dealing with BPCR Shooting, you best forget everything you learned about match rifle shooting. BP and Conventional rifle shooting is as differant as night and day.
I would recommend you go to a BPCR and talk to the shooters. They had some great ones at this match, One is on the US Creedmoor team, they are more then willing to help.
I just cast up a bunch of bullets, stuff the cases with powder, They shot pretty good up to 200 yards. They shot totally differant at 800-1000. Back to the drawing board for me, with my new found, humbling knowledge.
