That's the nicest .22 Rifle I've seen in a long time. I think it should be capable of marking fairly well out to 200 yards and more.
Aside from muzzle loading, I too (like Bob Miller) shoot long range .22 RF... However, my shooting is not for practicing for larger caliber long range events,,, I shoot the .22 for what it is. Lots of fun!
As a matter of fact I'm heading out in the morning to see how many hits out of 30 shots for record I can get on the 5" x 7" - 200 yard gong. I actually shoot at smaller gongs (5x6, 4x5, & 3x4) from 200 yards with good success, but tomorrow's internet match is what is stated above, 30 shot from 200 yards.
I would think that the pictured .22 muzzle loader would be capable of generating some very good accuracy. Is the .22 bullet paper patched?
