How MPBR is figured

From a rifle with a scope 1.5" over the bore, sea-level air and a G1 drag model. Every round gets a 2" small-game zone (squirrel head or body); the .17s and .22 WMR also get a 4" varmint zone. Sight-in height is given at 50 yards, the usual rimfire zero distance.

Keep in mind

Rimfire accuracy varies a lot by ammo brand; try several in your rifle.
.17 bullets are light and blow around in wind more than their speed suggests.
Velocities and BCs are typical rifle figures from my own knowledge, not looked up. Pistols run slower.
