Can't comment on the recoil question. Have fun trying! The M1 is a great rifle with an interesting history. However, focus distance and parallax distance are two different things and are independant of each other. The scope should be focused for the eye while looking at the sky untill the reticle is clear. There will be some minimum distance inside of which the image will be out of focus but beyond that range the image will be clear. But the reticle can only APPEAR to be at one set distance and in .22 scopes it is 75 feet. If the target is 75 feet away, and the rifle is motionless, moving your eye aroud the objective lens will not make the reticle appear to move on the target. The reticle is "on" the target. This is zero parallax. If the target is closer or further away, when your eye moves, the reticle appears to move on the target. The greater the distance is from 75 feet the greater the apparent movement. It's a matter of optical leverage. The reticle is the fulcum, your eye is one end of the beam and the target is the other. More expensive scopes have a knob or ring to allow parallax adjustment for any range but to be useful the range must be known. With a non-adjustable scope, if the shooter is careful and keeps his eye centered in the lens, there will be no parallex error. Truth be told, it's not a big deal inside 300 yds for hunting accuracy. Beyond that it pays to have an adjustable scope or to be very careful with your eye position. For competative shooting it can't be ignored.
