Saw a Browning A-bolt target with scope for $2000.00....new... online.
I searched the Browning site and could not find the twist rate of any Browning rifles. If you are looking at a .223 for shooting long range you will want something to shoot the heavy 80-90 gr bullets.
Before spending any money on a rifle I suggest you look into one of the ORA's Introductory Days in the new year. It will give you a better idea on what to look for in a rifle and may save you some big bucks in the end by not pissing away your money on a rifle/scope that is not suitable for long range work.
