Going off of Chairgun let’s say you were shooting the 10.34 JSB in .177 and 15.9 JSBs in .22. (Maybe you’ll shoot lighter pellet in .22 but it was the lightest JSB there was on the list and lighter will have a lower BC) Both pellets on there have the same BC so retained energy at 50yds is just over 8fpe with both starting at 11.9 at muzzle. The .177 is moving 140fps~ faster than the .22 so if I had to choose I would pick the .177. But also depends on what your targets are. Being I shoot birds mostly I’ve heard .177 is preferred as it penetrates better.
