I use heavier ammo in My air rifles. I have two PCP's intended for hunting use and they are both .25 caliber. As far as finding just about any pellet You may be looking for, Try PyramydAir.com. Now the lighter pellets shoot faster and flatter, but You can loose speed by using a heavier pellet and deliver a lot more kinetic energy as a trade off. Your .22 should have pulled the plug on that squirrel with just about any pellet used. My smallest pellet is approx 26 grain and got some cast up to 53 grain which used in My Sumatra gives a little over 100 fpe, wouldn't hesitate to take a hog with it.
