Short version, I ordered a can, I mean, a friend of mine ordered a Banish 30 from Silencer Central for his 300 Win Mag. After 10 months, it came.
First time at the range with it and WOW!!! Significant noise reduction AND recoil reduction! At 100 yards, it changed the zero about 2" horizontally, and maybe 1/2" vertically.
Second time at the range, I took some sound measurements with a phone app decibel meter. For each shot, the gun was on a Varmit bench rest. The phone was placed at the foot of the rest, in the same place, for each shot. I didn't confirm the exact position of the end of the barrel for each shot, and the 22 WM has a shorter barrel, so it was probably a little closer to the phone.
Anyway, here goes the objective part:
300 WM, Suppressed, 5 shots: 107 dB avg
Ammo: 165 gr Federal Fusion, muzzle velocity of 3080 fps
7mm Rem Mag, Unsuppressed, 3 shots: 120 dB avg
Ammo: 162 gr Hornady Superformance, MV of 3030 fps
22 WM, Unsuppressed, 5 shots: 118 dB avg
Ammo: 30 gr Hornady, MV not recorded
For the subjective part, I felt like my groups, I mean his groups were smaller. Didn't shoot the 300 unsuppressed, but IMO, it's not that the can made the gun shoot better, it's because the can reduced shooter flinch.
Regarding recoil, it felt like the 22 WM. WOW! Usually after about 3-4 shots with the 300, I'm done. But with the can, I shot almost a box both times. (I got the 7mm and 300 groups mixed up and adjusted the wrong way, so it took a little extra to get the 300 back on target.)
So short version, the can stays on all the time now. And I'll, I mean he'll probably spend more money on ammo now that it doesn't result in a bloody nose each session!
