I actually have both the Drozd, ( bumble bee ) russian BB pistol, and it is a hoot, anyone how shoots it just loves it, and it is pretty accurate for a BB gun and has never hiccuped, it just runs, and I have and 46 match pistol, got a good deal through a group buy, and it is very accurate, comes with repair parts and was under 200 dollars, but it is not a 500 fps air pistol, it is 300 and very gentle to shoot, now if it was .22 caliber, I think frogs would be no problem, .17 iffy. How about Aquila, colibri, or super colibri in your .22 pistol, these are quieter than a lot of high powered air guns, and it is a 20 grain bullet at 300 fps, I kill squirrels, ( not to brag but up to 72 now ) with my 16" contender carbine, just a shot behind the ear at 30-40' and out they drop. Cost you maybe 3 bucks to try 50 shots and listen to them in your gun, and see how accurate they are. Good luck. I need to do a video on the Drozd, it is bad to the bone, and so much fun. I actually killed a running squirrel with it, a BB gun, who'd a thunk it?
