I need to find our air gun enthusiasts on this forum. Need to know about if better to have 177 or 22 when talking about lower velocity guns such as 1377 & 1322. I am quite sure an 800fps 22 rifle has more FPE than say a 1000fps 177 rifle. However, when you go to shorter barrels and pumps, is it better to have the extra velocity of the 177 (say 550-650) or the extra weight of the 22 moving slower for hunting small game? I am thinking at "some point" the extra size of the 22 is offset by moving slower when you get into shorter barrel, lower powered guns? Then it becomes a wash and the 177 and 22 are about the same FPE in some cases?
