LOP is fine and it has a flex tech stock. I'm starting to worder if it is the report of the gun thats doing it.
Could very well be, especially if he isn't wearing hearing protection...
Like these guys mentioned, get down to 70-80grs, that's all that's really needed...The old 45/70 was a .45 caliber bullet over 70grs of black powder...Of course, that bullet weighed 405grs, so she did kick...
