I am testing Titegroup @4.2gr with 115gr FMJRN bullet. I am using a CZ SP01 or 85C. I have kept my OAL at 1.145 range. And I have tested in the barrel of the guns. What am I missing by not conforming to the listed OAL that are posted? I have shot at least 500 rounds at OAL of 1.50 with Power Pistol and had no problems also. Yes I am new to reloading.
