[QUOTE="Copper Basin, post: 1957179, member: 53829"] New load work for the 28SM. 83g of N570 was too hot in my chamber using ADG brass. Hornady brass was on the edge as well. I got 3234 with 83g of N570, BTO of 2.930 but I was getting some ejector kisses on the brass. I dropped down to 82g of N570 with BTO's of 2.900, 2.910 and 2.920. My MV's were 3206, 3206 and 3212. Accuracy was best at 2.910 (.070 off the lands). I still had slight ejector kisses. Bolt lift was fine and not an issue. Next loads will be 81.8g N570 at 2.910 and 2.920 BTO's. Almost done and staying real close to 3200fps with the 195 Berger Elite Hunters. [/QUOTE]
