I use plain jane flat nose wad cutter pellets you can get at walmart. Heck I've killed squirrels with it before. I will say my pellet gun aint a toy. Nothing exotic as it also came from walmart. I think it shoots something like 1200 feet per second.Thanks for this info. I've heard that you need like at least a real .22 for this, or if pellet a very exotic and rare one, whereas our plan was to just use one of the .177s that we have.
