It might be that the hammer in your Sniper II is rebounding off of your valve more than your older Sniper III. When you fire, the hammer hits the valve pin and opens the valve to fire the ball. When the pressure in the valve chamber drops for the shot, the valve spring forces the valve shut and pushes the hammer away. The hammer then strikes the valve again, much softer than the first time, and the can cycle repeat. It's kind of like an under-damped harmonic oscillation. The rebound in your Sniper III must be small enough where you cannot notice it, but in your Sniper II it’s enough to vent some gas after the ball leaves the barrel, making a loud “dry fire” like sound. This isn’t a problem in Autocockers because the back block catches the cocking rod before the hammer has a chance to hit the valve a second time.
I’m not entirely sure how you can correct this because I have never had to deal with this (I use an Autococker). Try changing your valve and main springs. I think a stiffer valve spring would help. Back in the day when people had this problem with older Sheridans, I believe they used lighter hammers. You might be able to find more help by posting on pumpplayers.com. There are a few hardcore sniper owners floating around in that forum.
