I am loading a Hornady 165gr BTSP. The refference to the 110 gr bullet was jus that, a refference to show that if if tried to load it at the Stated COL it would simply set atop the case.
FRom Hornady reloading manuel edition 7 page 471.
case length 2.494
Maximum COL 3.340

From my measurements the Hornady 110gr SP is 0.825. Add that to the 2.494 and get 3.319 or .021 would be inside the case neck.

AGain the 110gr bullet was just to show what would happen if loaded to the Max COL. So back to my original question, am I loosing accuracy(in my bolt action) by moving the bullet back to the canelure or should I load to the Max COL for max accuracy since at MaxCOL my bullet is not touching the lands???? Is there other ifo that is needed.
