And the OP has very little time behind a rifle. So does he need the supersport motor to start off with? And I know there might be a difference in accuracy but it is still a .22 and with bulk ammo it is pointless unless you are shooting match grade ammo. If he is looking to shoot maybe 12 times or less a year them I would say he does not need a green mnt, or whistlepig set up. For the OP here is where you need to go for info on ALL .22lr good site for info. http://www.rimfirecentral.com/forums/index.php
