Well I think I might have to bite the bullet
(pellets??) on this one. BWT is .050 with bores .720 and .722. So, since I'm "buying the barrels" it seems they will do the job. Taking a few roosters with a lifter hammer gun seems like it could be an enjoyable day's work (provided the bureaucracy can make it all happen before the season ends
).
Cheers,
Jack
