Gadget54,
Good point!
I was a huge airgun addict for a long time. Through the years, I had Beeman Magnums R1, R10, R7, a Kodiak .25 cal., (I can't even remember all of them), and assorted Sheridans. I liked them but they were very expensive, fairly loud and heavy! That was before I discovered the wonderful world of subsonic .22's!
Standard or hyper .22's, (and even shorts), can be pretty loud. Subsonics have been around for a long time but until recently I never gave them a try. They are SUPER QUIET and most aren't even as loud as a regular pellet rifle! They now come in a lot of different loads and as Gadget noted, can even be had with just the primer as the propellent and are virtually noiseless in standard length .22 barrels.
I live in a very secluded, rural area and have quite a few ground squirrels around that are real pests. I had dinged quite a few with with my pellet rifles but usually only precise head shots dropped them with any frequency.
A few months ago I had a chance to buy an old Stevens Model #15-A single shot, bolt action rifle at a ridiculosly low price. I then bought some subsonic hollowpoint .22's. WOW! Talk about QUIET and DEADLY! Forget about being quieter than ANY pellet rifle I ever owned, these things are quieter than most cap guns! Deadly? You can even forget head shots, these things drop those pesky ground squirrels right now out to about 50-75 yards! At least I get these results in my 24" BBL old Stevens.
Now I'm not saying not to enjoy your "adult" pellet rifles but even a quality, new, single shot, bolt action .22 rifle is a heck of a lot cheaper than a adult air rifle. You can also get subsonic .22's for not much more than quality pellets.
Just be aware though, subsonic's won't cycle your semi-auto .22 rifles and work best in single shot bolt action's with barrels of 20" or better.
no i dont know the exchange rate, its a diana something i dont know the model
, I generally try to limit my high powered air rifle shots to around 50 yards. YMMV
