Built mainly for fun and to shoot at local Field Trial Pistol Match.
It currently it shoots a 14.3 Crosman Hunting Pellet at about 530 fps in a 72 degree room for 8.92 FPE.
Make sure the 8-32 threaded section of the bolt handle is not too long and causing the bolt to bind against the inside of the breech. (ask me how I know) It only takes a tiny bit of the handle passing through the other side of the bolt to cause it to bind.
