I have found with my CZ rifles and SV ammo that a 50-yard zero will strike a 17-yard target with approximately the same POI as at 50 yards.

Longer sight radius compensates for speed loss

Common wisdom dictates that a .22LR round achieves maximum velocity at a barrel length of about 16.5", and any added length slows the bullet.

I have three CZ455's: Varmint (20.9"), Training Rifle...

It's directly below the exposed part of the bolt

My 455's are all stock, and I locate the magazine well by remembering that it is DIRECTLY below the exposed part of the bolt. I don't understand your difficulty I guess.
