22-284

I would agree, you have plenty of twist and velocity to shoot the heaviest commerical bullets out there. Many of the thin jacketed bullets like the A-Max and Berger will have a velocity ceiling of around 3250 fps. This is not a given but very common, especially with a 1-8 twist barrel.

You may want to try the 80 and 90 gr SMK.

Another idea that may be worth trying is to get some of the 100 gr ULD RBBTs to try. I tested these in a 1-7 Lilja. They were limited to 3100 fps in that barrel but it was a three groove. In a 1-8 6 groove, you may be able to get a bit more velocity. 3200-3250 fps with a 100 gr ULD RBBT would be a very good thing in a 22-284 compared to a 75 gr A-Max at the same velocity if thats all that barrel will allow this bullet to be driven to.

I can not say 100% that the 1-8 will stabilize it but it would be worth a shot to see. The 90 gr SMK should definately work well.

i'm not familiar with the 100 gr ULD RBBTs. Were could a guy get some?

It here finally. I started wish 52 grn of h870 now i'm at 56 grains of h-870 with a 75 grain a-max. Groups are around .75 but I think mypressures are getting close to maximum. I want to try a couple different bullets and see were we go from here. i also tried 53.5 grains of imr 4350 with the same bullet didnt group worth a poop. Wondering if it wasn't pushing fast enough to stabilize the bullet need to work on this load. Want to try some vvn550 going to start with 39 grains and work up. Keep you posted. John
