Buttplates and hooks
Hook butt plates are not allowed at all on a match air rifle, and the curvature and fit rules for air rifle are such that you will not get any real advantage using a modern butt plate such as a MEC 111 or a Gehmann, over the standard plate fitted to your LGM 1.
If you want to improve, work on your position and balance. Look on page 28 & 77 of my book.
Best of luck and have Fun.
