Thread: How to make my .22 quieter

Before I started sporterising my bsa martini international, I did try the original long (27"?) barrel and ot seemed relatively quiet. Suggest the extra length barrel was letting the gases expand and cool down for that fraction longer to help.
Also know of someone with his Russian 22. The model that seems to shoot well as its based on a target rifle but having an elderly moment and it's name escapes me. It consistently put those CCI subs just supersonic.
It's been several years since I tried them at his place but something is niggling that it had quite a velocity spread through my 10/22 across the chrony.
50 or 60fps rings a bell
