Re: savage 99 .308
The savage 99 is a great hunting rifle. It is a bit lacking as a long range rifle. Velocity and accuracy aren't going to be on par with a quality bolt action.
Still, see how she shoots. Let the gun tell you what it can do.
If you have a Savage 99 in 308, and would be interested in trading for something better suited to long range, I have several long range rifles. A nice 99 has been on my list for a long time.
