I bought a new Savage smooth bore 22 rifle/shotgun a couple weeks ago.
This thing is a blast! I always figured a smooth bore 22 would be fun, but this thing is seriously a blast to play with. Starlings at 25-35 feet are pretty much history after taking several of these little pellets. A field mouse will literally roll after taking a direct hit at less than 20 feet. It shoots a decently round pattern tight enough for nearly any pest control needs within 10 yards.
I'm thinking seriously about taking it to a local smith, and seeing if he can roll a slight choke into the last couple inches of barrel. If I could stretch the ranges to around 40+ feet, I feel pretty sure it'd still have enough thump left to reliably anchor rats, or starlings at those ranges if multiple shot hits them.
I haven't tried it on BEE's but I'm quite certain it'll put me on a whole other level of performance. :-D
