I'm working up a load for my RPR 6.5 Creedmoor using small primer Alpha brass. I'm using H4350 and 142 Sierra HPBT and 450 primers. Tonight I worked up to 41.2 grains that gave me 2660 fps. The brass shows no pressure issues and I was planning on going on up .3 at a time. What is thought to be the max with this brass and powder? I would like to get up around 2700 or so. I got my best group to date at 40.6 around 2620 fps. What is everyone's experience with this load or similar. Thanks Sierra lists mx load at 42.3 but maybe not with Alpha brass?
