Target shooters . . . HELP ME PLEASE!

[c east]

I use to shoot Glass bedded M-1 garands and a lot of semi autos and one rule still works....I don't know why....Shooting with the for end on the bags will get a lousy group...Even taking care to place the rifle at the same spot on the front bag, like bolt rifles ....Lousy groups....Taking the same rifle, ammo and all and placing the fore end in my hand and resting the back of my hand on the bags made a lot of improvement....try it....Charlie
