I swear Jerry Miculek was inhuman for his innate shooting abilities and I think this video is the true proof that Jerry is indeed – not human. If his plan was to keep his machine construction a secret he failed.
Or, its possible (but highly unlikely) that Jerry is actually human and just that good. To prove it again (as if he had to), the Terminator showcases a classic spin cock on a M1887 shotgun. Its suitably bad-arse and proves that Jerry can do nearly anything ballistically possible.
