Are these things better than mini mags?
For the vast majority of shooters and situations? Not really. Anything you can do with a Green Tag, you can generally do with a Mini-Mag just as well. For hunting, plinking, and general target shooting, there's no real difference.
If you're talking about high-precision match shooting or competitions, then yeah, you'd probably be better off with Green Tags, just to give yourself the best possible edge.
If you think Green Tag is expensive... stay away from the RWS/Eley/Lapue ammo...
