Recently, I tested some handloads and had a POI change with a different bullet type and wondered what this is telling me.
The background: I was testing some AR .223 loads at 50 yards. Same powder (Win 748), different headstamp cases, same weight bullets (55 gr.). I was shootiing different charge weights for each bullet type.
Shot a few foulers with FMJBTs - POI right around center.
Shot a number of Hornady spire points across 5 charge weights - POI generally around center.
Shot a number of Hornady Z-MAX across the same 5 charge weights - all POI groups were consistently below the center about an inch or two (don't have targets in front of me).
I am curious if this is tellimg me anything about veloctiy between the SP and Z-MAX bullets. Thanks in advance!
