I’m using 4831sc in my 280AI with Peterson brass but keeping it at just over 2’800 to keep from destroying the primer pockets..I am using H4831sc powder with a Berger 175gr. In my 280AI 1@8 26-inch barrel. I am getting 2900+ fps. But I'm little over max. 4 shot groups. I thought i had loaded up 5 rds of each load. But didnt. N560 would be worth a try.
