Its a case of try them and see if they are both grouping the same then go for the cheaper accupels. Unfortunately 2 of my rifles only give good groups using Premiers accupels are like a 12bore at 40yds and the JSBs are nearly 1" groups at the same distances. premier die #7s give 1/2" at 50yds.

Would rather the rapid would use JSBs but it seems to be very pellet fussy.
