The advertised muzzle velocity isn't an exact number. It'll vary according to a swarm of variables.
"...out of my 22" barrel..." Remington probably used a universal receiver with a 24" barrel.
"...calibrate the hash marks on my scope..." MV has nothing to do with that. That's done on a range. You want to know where a shot hits at specific distances when aiming with each mark. As in how much hold over is each mark.
Forget any ballistics program. There are far too many variables involved.
Spelling and grammar count!
