HP I noticed the lug screw problem last night when I was cleaning it. If you tighten them too tight, you can not even cock the rifle. There is a set point where the screws allow the max travel of the striker while at the same time keeping the barrel in place. Also the ram rod needs to be in the holder when you shoot....

That would explain why it shot dead center but a little low. I will have to go back out and play somemore with it. I was shooting a different rifle today. Thanks for the heads up.

I also ordered a; Quickee scope rings and bases made for the Black Diamond today, and the extended view Dusk to Dawn Bushnell Banner Shotgun Scope for it. I figured that would be a good low powered scope to put on it. I decided I did not want the Tasco I was planning on putting on it....

I will be interested in what loads and charges are working good for you.
