Played with the 500 A-Square today, mostly to fireform some brass but had a blast (no pun intended)!

Load: 817gr surplus spotter bullets (green tip), Weatherby .416 brass, Winchester large rifle primers, 70gr Reloder 15.

Results: 3" at 100 yards from a bench using a Harris bipod. Low recoil. Nice flash/bang on impact. Very fun!
