M&P CORE Ported Performance Center - terrible accuracy SOLVED page 2

Solved!

Went to 4.3 gr Titegroup and 1.135 OAL, also tightened the crimp a bit to .376. 10 shots from 15 yards with 8 touching

Glad to hear it. If you want to test your crimp for the plated bullet, simply pull a round and inspect the mark it left on the projectile. You only want the slightest faint little line. If you have a very distinct line or groove, you have to much crimp which can and will effect accuracy.
