I have a 22LR barrel, using it nowhere near as much as I'd like. For the price of the barrel alone (not to mention mount) I could have bought a quality 22LR rifle plus scope or even a more useful calibre such as the 17 HMR or similar.
The dog is a german wirehair. I think the main difference with the silencer is that the reaction we refer to becomes more reliable. It is a little difficult to be empirical, but pre-silencer I shot 7-10 deer a week, now I take 3'ish a day (weather permitting). I simply get more chances.
