RTI Hush Moderator bad groups.

Not the RTI mod, but just had a similar experience with a 0db mod, changed to a donnyfl fx mod and back to grouping. This was with a Prophet Performance, MRD’s @ 970fps.

You should have said something before wasting all that lead. The very first thing you do when a new gun isn’t grouping is clean the barrel. The second thing you do is pull the mod.

I believe there are 3 felt wrapped baffles in the 0db, and it was a .25 cal mod, on my .22. No evidence of clipping.

You don't need to clip to have accuracy issues with a moderator/shroud. It could be nothing more than barrel harmonics, but more often than not it is an alignment issue, whether it is bad enough to clip or not. With my firearms, I never shoot with a suppressor without checking each firearm it will be used on with an alignment rod, of course firearm suppressors are a huge investment and you would be a fool not to check. An alignment rod doesn't work with a choked pellet barrel, but would with a non-choked barrel. An easy, fast, and cheap way to check alignment on a pellet rifle is with painters tape. Tape over end of suppressor, then using your finger, smooth object, whatever, push around endcap opening on the tape to get a good crease. Shoot a pellet. My 22 Uragan was horrible with the AGT moderator on the end of the shroud (shroud flex with moderator added), I fixed it and it now looks like this and works perfect. Anything close to the edge creates high and low pressure areas, which means high and low speed gasses. Never good for a pellet, or even a slow light chunk of lead. Had to have the shoulder of one of my threaded 22lr's adjusted by less than 2/10,000 to get it centered and make it shoot well with a suppressor mounted. It was not clipping, just a little to close to edge of endcap.




The green frog tape works, but it shreds a bit, just push it back down and see the center. I printed concentric circles on the green frog tape.

THAT HUSH LOOKS CHEAPLY MADE
