I shot the 2-1/4 oz #7 hevi's yesterday afternoon. The temp was 70 deg and the humidity was 100%. At a lasered 40 yards, the results on three consecutive shots through a fouled barrel were 292, 273, and 270 in a 10" circle. An average of 278 is not bad, but not what I was hoping for. I will test again with a clean barrel. If I can get it above 300, i will test it at 60 yards.
