Hello Everyone. I have been shooting USPSA for a little over a year and have been reloading for my STI edge and a bar-sto since I started. I have never had an issue developing loads that meet power factor and function in either gun...A few months ago, I took delivery of a custom 2011 with a briley barrel. This barrel has me stumped....The most recent load that I have worked up is 4.8gr of n320, loaded at 1.180, win primer, xtreme 180gr HP. This load comes in at 166PF and is showing signs of pressure. Flat primers, and primer flow...If the primers did not look they way they do, I would normally bump up the powder 1-2 tenths of a grain and call it a day..One of the guys at the range mentioned I may want to test magnum primers for more velocity..
Does anyone have a similar experience with briley barrels? They seem to be slower than STI and bar sto barrels..Should I try jacketed bullets or a different powder?
Thanks for the help in advance.
