mini: I cant find any CCI Mini Mag ammo .22lr 40 grain at Bass Pro here in canada but they do have the same in green tag whateve that means, it too is 40 grain. I need clean and good ammo for my Rem 597.What difference is there with CCI 22lr Mini Mag ammo and the same with the green tag name?Green Tag is Match Grade. It should be more expensive. It is also nearly 200 FPS slower. It MIGHT not cycle a semi-automatic reliably, depending on the gun.And while the Green Tag it is designed to be more accurate, the CCI Mini Mag is better than most everything else in my Kimber .22 Conversion Kit and has won many local matches. I've yet to try Green Tag, but the Mini Mag is beating several other brands of Match Grade stuff, including Remington, Aguila, and Wolf.What difference is there with CCI 22lr Mini Mag ammo and the same with the green tag name?Mac pretty much summed it up. Just wanted to add, the reason Green Tag is more accurate is that tighter tolerances are held during its production and final inspection. That plus the slower muzzle velocity in .22 RF make for a more accurate cartridge.
