So i'm a fairly new precision benchrest shooter before I develop a poor technique with my non shooting hand I would like your inputs on exactly how I use my hand. What i've been doing is using a simple Champion rear bag with a piece of 3/4" plywood as a spacer. I then lay my thumb on the bag and grip the ear of the bag. I then rest my buttstock on my thumb. I can manipulate the elevation by gently squeezing my grip. I realize this is not the typical method used. It seems to be very comfortable, stable, and repeteable for me. Do you think my method will hinder my accuracy advancement ? Thanks !
