Thread: .22 with subs, how short and what suppressor?

These are 14", they hold subs at sub velocities pretty reliably (maybe 1:100 rounds goes "crack" with CCI, less with Eley match etc).
@Kiwi-Hunter cut his to 12" and its about the same, however his gunsmith cut a 1/2x28 thread on it to suit a suppressor he had at hand and now its too short to cut a new thread, point being if you "fly close to the wind" sometimes it can bite you further down the track
