[QUOTE="shooters, post: 2884851, member: 7769"] I have a 300 PRC and running 230 Berger and N570. 22” Bartlein barrel. Defiance action. ADG Brass. I’ve loaded 79g up to 84g of N570. Sometimes I feel like it’s hard to tell by brass alone if I have pressure with the ADG since it’s so hard. At 82g, groups start to open up. Like 2” groups. At 84g, it’s pretty much horrible. At 79-81 grains it’s a 1/2” gun or better. I would like to run them a little hotter if I could. Right now with the 81g and 230 Berger out of the 22” barrel is 2814 FPS average. Good SD and ES. The 84g was 2905 average. This is a built rifle with defiance action. I’ve never had a sticky bolt from too much pressure on any of my built rifles with the finance actions. Usually the first signs of pressure I noticed in the brass, but like I said, it’s very difficult with ADG for me to tell. So my question. According to applied ballistics, the 215g is the better option unless I push the 230 Berger to 2900. So, can someone tell me by looking at the brass alone of the 230 Berger with 84g of N570 is too hot? [/QUOTE]
