A shotgun would work if you aren't too close.
With a .22, I'd use a solid bullet and not a hollow point. Possible a .22 short, but be sure your gun is sighted in with the short. It will hit different than the .22 long rifle.
I'm going to guess $150-$200 for the mount.
I did one for my nephew a few years ago. Did a black one for his father too.
