Checking load data from accurate's site it has ....160gr barnes bullet with 9.1gr of #5 (oal 1.254) going 1144fps out of a 5" barrel. For me out of a glock 3.8" barrel it almost reached 1000fps using the same primers(150). This is listed as a 45acp+p load. I had to work up to 9.6grs using 45super brass to even reach 1050fps and don't feel good about going higher as the primers are starting to show signs. I guess the published velocity is impossible to reach safely in a glock compact barrel,but thought I could get closer with this powder. Wanna kill these ads? We can help!
