one last thing...very rarely does an airgun reach its stated velocities!...to get those 'advertised velocities' they will find the tiniest lightest pellet they can to get those numbers....be wary of that...
any airgun manufacturer that will post its 'ft/lbs' capability is much more accurate and you can then back calculate what the actual speed will be with certain weight pellets that you will actually use...
all those guns that claim 1000 fps etc. usually a bunch of crap...a real world stout springer that will push a 7.9 grain .177 cal pellet at 800 plus over the chronograph is a stout air rifle!...thats 11.2 ft/lbs at 800 fps, not many springers will do the 17.5 ft/lbs necessary to push the same pellet at 1000 fps! so keep that in mind.
many springers will do in that 12 ft/lb range, typically a .22 cal version of the same rifle will retain a bit more energy...ie; if pushing a 15 grain .22 cal pellet out of the same rifle that pushed the .177 cal pellet to 800 fps would probably go about 600 fps or 12 ft/lbs energy....same rifle, same spring...go to bigger pellet and the larger pellet is able to hold a little more of the energy than the smaller pellet is all.
i'd love to have 600 fps in .22 cal vs the 625 fps in .177 cal that i have but can't find it in such a small, light, nice and fun to shoot little air rifle...so i know i have the penetration capability but just not as much 'thump' as the .22 cal pellets can deliver...so shot placement just a tad more critical for me...my little rifle is doing 6.9 ft/lbs energy fyi....
i'll bet if you chronographed most rifles claiming 1000 fps with a standard 7.9 grain pellet...you'd be aweful surprised what they actually did for speed...so don't get your hopes too high...you only need about 350 fps at impact to kill the critters you mentioned...and even my little rifle probably maintains that speed to over 50 yrds or more...with only 625 fps to start
beeman sells my same rifle under their own name as the 'R7' i believe...they have a bit of a cult following from what i remember as a very under rated air rifle and one of the most pleasant to shoot etc....and i totally agree, nothing fancy, nothing flashy but it works and is a joy to shoot
