Hey Casper,
I just started shooting the 5.7 outta my 12" Bullberry barrel on my G2. Haven't done a whole lot with it yet but it seems to be pretty accurate. I have a few groups under an inch at 100yds and I'm sure i can improve on that when this DARN weather straightens out! I can shoot water bottles all day at 150. Alot of people refer to it as the "centerfire .22 mag" and I agree it is close, but remember the 5.7 is also reloadable. Its to late in the season to hunt "chucks" but I'm sure its more than enough for our coyote season at reasonable ranges. If your lookin for someone to talk ya into it, I definatly give a 2 thumbs up if not just for the fun factor!! GOOD SHOOTIN!!
