I've shot it 3 times out the back door. The gun recoils straight back and I actually saw the pellet holes appear in an oil can. I'll shoot for tight groups as soon as I get it shot-in. Have the Straight Shooters Sampler and use the Match, Pointed and Hollowpoints to help break-in....

I gotta tell you though that the seal had been damaged during assembly and was the reason for the lower than normal pre-tune velocity. My wand didn't do all of that :)  :)

Charlie, you and Rich are as bad as each other... never wanting to take all the credit for
transforming an air rifle the way you guys do....... but we all know that ya'll have those
bags of magic potion hidden in your workshops.  :D
