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

I want to chop my .22 bolt gun quite short for making easy in vehicles etc. It will be for subs only, but still want to be maximize potential velocity (around 1050fps) from Winchester or CCI subs (or what ever shoots best).

How short can I go with the barrel and still get good performance and accuracy? At legal minimum length it will be just over 11". Do I need it to be longer?

Also what brand suppressor? Given subsonic ammo are dirty I want one that can be opened up and clean and also it will go onto a .17HMR one day. DPT and Kaimai (I know, I know...) both look pretty good. What do you prefer and are there any others to consider?
