I purchased this rifle in 223 about a year ago for varmint hunting and prairie dog hunting, and also I just turned it into a long range gun, even with this sps stock I get very good groupings out too 800yards. I've never tried farther. Even using cheap Russian ammo it still preforms well and I'm very pleased! I'm buying this rifle in 308 for big game hunting and long range shooting because I know it's an excellent rifle and just as good as a $4,000 rifle. Buy this rifle, you will be very pleased I guarantee!
