I have the .22 conversion kit for my M4 to save on ammo and I can plink
for hours on the cheap. Also the ranges don't mind rapid fire with .22s because the noise
doesn't alarm people wearing ears. That's two bangs for my buck.

And I carry a Bobcat as a backup with this round. It has just about
as much lead as a .32. Very effective at close range.

is it not ‘rifled’ ?

At 50 feet that looks like the bullet was spinning sideways

I nice circular hole would indicate good rifling (much better accuracy and much longer distance)

on the other hand, a bullet spinning like that would make the person on the receiving end a lot less happy
