Yes, I meant muzzle flip......but if you held the M1A with just your trigger hand and fired, you'll feel one type of recoil and muzzle flip.....then hold two handed, at the mag and you'll feel another, different, recoil and muzzle flip....then hold two handed, out by the sling swivel, still another, different recoil and muzzle flip. The name of the game is to get it on target and keep it there, shot after shot.
We have a COF that we call the Grinder( or the Swinger), that tests this very thing. We have 4x8', free standing partitions( most ranges do) to simulate walls. We run them parallel to each other( about 5-6' apart), from the starting point( of the firing line), down range. We'll put 2, then a space( on either side) and then 2 more, then a space, then 2 more, so that you end up with a "hallway". Now, at the spaces and 45deg off that, we put 2 targets, sides by side, about 15 yds away, so that when you start at the starting point and walk down that "hallway", you come to those openings and see 2 targets at the 45, on either side and 4 side by side, down at the end.
So the COF is , at the buzzer, quicky walk( or run) down to the first opening, swing up and put one in each target on one side( doesn't matter which side), swing over and put one each in the other 2 and then swing back and put one in each of the first two and then swing back and put 2 more in the second two, so that all 4 targets get 2 shots each. Then quicky on down and do that again at the next opening......Then, down at the end is 4 targets, side by side, you put one in each, Done.. 12 targets, 20 rnds, if you use 10 rnd/mag, you can add a mag change.
Score is for time and accuracy.
This will tell you where to put your hands.
I guarantee that right after the first string( maybe sooner), most hands will spread out.
