Had Bullberry make me a 10" 218 mashburn bee. Was surprisingly finicky on what bullets it liked even with a 1-12 twist but when I found that 40 gr sierra sp's were the ticket it wouldn't miss headshots on the 150yd turkey silhouette. I think a 10" 221 fireball would be the same only better. Slightly larger case is easier to handle in the press and not quite as finicky with powder charges.
A 32 H&R mag or 327 Federal would probably be the ideal cast bullet plinking and close range small game round. A couple grains of powder and 100 gr of lead for fun, ratchet it on up to make fur fly.
