Daystate Wolverine Hi-Lite .22 and a Decibel Meter
You can spend your entire life testing airgun report if you desire. Simply pressed max db on the meter, and placed accordingly.
Here are some numbers from a Wolverine Hi-Lite .22 @ 230BAR (do not have chrony numbers) in a suburban backyard. I'd say the backyard is 27Lx15W in yardage. I shot in the center.
Shooter: 105, 105.8 (multiple readings - these are extremely close averages)
Muzzle: 100.7, 101.5 (multiple readings - these are extremely close averages)
Impact zone: 98.8 (bottom of fence - I know - Don't lecture me - wanted a good smack)
12 yards behind gun: 70.3
10 yards perpendicular from gun: 78.9
Corner of fence-line (I'd say 10 yards in front of gun, and 10 yards to the right): 79.7
One reading inside the doorway from muzzle (Of course no one does this when game presents itself): 100.9
Need to order Different scope covers for the Bushnell Nitro, as the one that came with the scope is way too tight to even get halfway on.
