Length of time for action to settle in new stock
I recently bought a new E2 stock for my M1A. With the old stock it would shoot 1 to 11/2 inch groups all day with 168 SMK over 42 grains of IMR-4064
With the new stock the rifle is shoot patterns not groups.
The rifle locks up tight and the hand guard has 20 to 30 thousandths clearance.
So how many rounds do I need to put down range to give the rifle/stock combination a fair shake before I try something else.
