My wife gave me a 17 Mack 2 barrel for Christmas. I had JD Jones cut it back to 10" and mounted an old Tasco 6X 30mm target scope. The weather has bee to wet to shoot so I took it to our indoor range. This barrel is a one holer at 25 yards. I can't wait until I try it at a 100 yards. The CCI ammo was alittle tighter than Hornadys'. This will be my new Squirrel gun.
