I just received a suppressor and have installed it on a Ruger mk IV 22/45, but accuracy seems inconsistent.
Groups shot without the can are much tighter than when shooting suppressed.
Is this an ammo situation (Federal 45 grain sub sonic semi-auto) or do suppressors need to be fully cleaned after 100 rounds?
Just trying to figure out why accuracy is so hit and miss with this set up. 2-3 shots out of 10 are way out of the group, as in off the steel plate. The other 7-8 shots are acceptable, but still not as tight as with the can taken off. Even with the same ammo.
Does anyone with more experience have some advice on this?
