I am a Law enforcement sniper and the previous posts are right on the money. Almost all snipers in Law Enforcement or military shoot the Remington 700 with a Leupold tactical scope in .308. Most sniper teams I have trained with, if not all have used the Federal 165 or 168 grain match boat tail rounds.

Most of the rifles have different barrels and tripper work along with a harris bipod. Our rifles have krieger barrels on them and trigger work by Charlie Milazzo.

My factory rifles for hunting all have Leupold scopes and trigger work. I use a Remington 700 stainless synthetic DM in 30-06, and A weatherby in 300 Win mag. The factory barrels on the higher end Weatherbys are Krieger Criterion button barrels. I'm pretty big on optics so spend the money and buy a good scope. Trigger work will also help. Get rid of the "creep" and have it set between 2lb and 4lb. If you are a newer shooter I'd lean much closer to 4lb. Our sniper rifles are 4lb.

Another big help is to make sure the rifle is free floated. That means the stock doesn't make contact with the barrel. You can check this by sliding a dollar bill between the stock and barrel it should slide almost all the way to the action.

I hope this helps!
