I would if we could. That's a good shooting sporter, Curl.

Nice group. Even better than my agg's with my rebarreled 10/22. It's agg'd .222" at 50 yards, smallest group .185". The .17HMR Martini does better than both, but is noisy, of course - agg'd .175", best of .153" matching that .22. THAT's gread for .22.
Sorry - that group got me excited - love to see rimfires shooting like that.

Appears to touch the 3/8" line which would make it .375" - .222" = .153" - or .154" if .223" groove diameter.
