I honestly would save mooney and skip on the polymags. The gun wont have enough power to get the full performance out of it. Preds out of my disco will blow HUGE holes in pest but out of my 2240 pcp carbine its jus the same size hole as an other pellet would give. congrates on the gun. I want to get one real bad. as for pellets my 2240 likes jsb exact 15gr and CHP alot, same with the 2260.
