Yea it will be an Extreme 16" and ER Shaw SPCII 1:11 twist 16" SSAs Richard said, 30-30.5gr 10X but only in 11 or 12 twist DMR or SPCII chambered barrels, start a little lower and work up.
You will have a hard time reaching those velocities with H322.Yea it will be an Extreme 16" and ER Shaw SPCII 1:11 twist 16" SS
I've got one of each coming. When I work these loads up I should be ok on CUP pressure? What should it be around? I shouldn't see any brass or primer deformation?
Is 10x a good powder for 68 overall? Can I get the same with H322?
