[SUP]I am loading 124 grain TC hitek coated bullets and have a question on COL. Could not find much data specific to coated bullets. Eggleston munitions had 1.100 on COL and universal powder 3.8 to 4.3. They did not drop in my M&P barrel and have room to turn until 1.088. How short can I load them before getting into over pressure issue? I shot test rounds set at 1.100 with no issues but they did not fit the barrel like the longer manufactured stuff. Just started reloading and don’t want to learn lessons the hard way[/SUP]
