Wasn't sure if this goes under pistols, rifles, pellets or what so I'm putting it here.
I'm someone who wanted to believe that a heavy 177 fired from a stock 1377 might have the same or better penetration as the slower moving 22 pellet from a 1322 or 2289.
However, in some recent testing using un-opened baked beans cans turned horizontally shot with the same style pellets of various kinds at 5yrds, 10yrds and maybe about 17yrds, the 22 wins every time. If you give the 177 more velocity from a better gun, it is plenty of penetration. But I was trying to see if 177 at a lower FPE than 22 from the SAME power plant could have any penetration advantage.
My testing showed that of the pellets I had available, the 14.3 crosman pointed, domes and gammo rocket (14.5gr I think) penetrated better than 10.5gr 177 OR 13.7gr 22 OR 17gr 22 pellets.
My goal was to see if I had a 13xx gun in the boat or the truck, which caliber would allow for a point blank head shot on an animal larger than should be normally taken with this gun. I may just need to kill a snake, but I want to have the most penetration available in case in an emergency I had to mercy kill an injured animal or something. That of course will probably never happen, but since I am partial to 177, I just had to know the truth.
I think a 177 with the SAME FPE as the 22 would probably penetrate as well or better just like how the Brits prefer 177 @ sub-12PFE when compared to 22 at the same FPE. But when comparing 6-8FPE in 177 against 8-11FPE in 22....the 177 smaller head size and higher velocity doesn't matter as much at that power level. I definitely had hoped for the opposite result, but my carry-all pumper is definitely going to be a 1322 or 2289 (I own both). I tried 10 pumps and also up to 18 pumps and the results were always the same. It took 17 pumps (at 10yrds) for the 177 to penetrate the thick bottom of the can of beans and the 22 could do it with 10 with most pellets (I did have a few inconsistent results at times).
I shot the can with a 900+FPS 177 and it was of course a whole different ballgame, but a 900FPS 22 would still probably penetrate better. There seems to be a sweet spot where 177 can out-do 22, but it just isn't possible with stock power 1377 from what I've seen...I'm not sure what ballistic gel would have looked like, but I wanted the hard metal to simulate skull for my hypothetical situation that will probably never happen LOL.
