Yep, Mini Mags work great. I mostly shoot CCI Standard Velocity in mine.Those that have the Shilen with the Bentz chamber, are you able to fire CCI mini mags and the like? Not CCI stingers or other more "hyper" ammo. Just regular super sonic stuff 36gr around 1235 fps.
YUP,. I Own one, a 20 inch, SS, "Sporter" weight, Green Mtn and IT, "Shoots" 5 shots into, sub 1/2 MOA at, 50 yds with, most Mid Priced, Wolf Match or SK Standard Plus Ammo with Group's in, the 3's / 4's NOT uncommon.Green Mountain makes a very good 10-22 sporter barrel. Don't own one, but the people who do seem happy with the accuracy.
