220 SMK bullet drop same as .22LR out to 200 yards?

[grey2112]

Been looking at getting a Pride Fowler 3-9x32 scope with BDC calibrated for most 36-40 grain hypersonic .22LR ammo (they say around 1260 fps or so it what they designed it for).

Now, I read here someone saying that the ballistics and bullet drop of a 220 grain bullet (SMK) loaded at about 1050 or so FPS is quiet similar to the .22LR's bullet drop, at least from 50 yards out to 200 yards.

Is this indeed the case? The PF reticle is supposed to be dead on at 50 yards and then the reticle drop lines go out to 200 yards and is supposed to be pretty close for most .22LR ammo.

If the 220 SMK subsonic is very similar, I think I found my scope.

grey2112,

Go over to this page and go through the calculations:

A typical BC for 22LR bullets is anywhere between 1.4 to 1.5.

If you load the 240 grain bullet to 1050 fps the difference is less than about 0.5 inches out to ~190 yrds. Out beyond that the 300-221 Fireball shoot flatter because of the higher BC of the 240 gr bullet

opps screwed up the decimal point The BC for a typical 22LR is 0.14 tp 0.15
