I did a quick test today of 4 mods. 55º, FX Maverick, .22 500mm barrel. #2 Reg 128.4bar Air Arms Diablo Field Heavy 18gr pellets 940fps A 'sound meter' calibration unknown but matches my iPhone. appox. 18" away, perpendicular to the muzzle. I only fired one shot for each and checked the POI as best as I could, all 4 had basically minimal effect on POI so that's out of the way, My gun doesn't like the AA pellets, my Sapsan LOVED them and I've got a ton of them....IF I ever get it beck from good old Joe B. from having a faulty reg. The Mods are skinny because i've got a larger bottle that I have to clear.
No Mod 116.9
Buck Rail 120.3
The Sabroia off of my Sapsan 116.4
Donny FL Koi 108.1
Impulse with 6 segments 115.5
Now, in fairness there is a hard table under the muzzle. Impressions, the Koi was the 'quietest' it removed the sharpness, the Impulse was next, I've been using this one with people on the other side of the fence, no comments. My Sapsans' Mod was ok, the Buck Rail was a WTH, gut feeling is, with a lower air volume it might work but it shocked the heck out of me with the report. What you don't see in the photo is my house to the right about 20'.
I had a chance to try some Orion mags, one was dead perfect, one had a very slight hickup when inserting pellet into breech. Loading was moderately easy, it'd be perfect with some little nubbies to stop my old fingers from slipping as you rotate it. I think I like them. I also have some CARMs, both have their strengths, with the CARM the pellets don't fall through but they have a slight misalignment also and they tend to slip with my old fingers, I'll probably have to sand off the bottoms a touch. Haven't gotten around to it yet. I think the finish on the Orions is better,
