I have two, one an older Model 700 BDL varmint, great rifle but limited to light bullets as it has a 1:12 twist barrel. Don't want to rebarrel it as its the rifle I carried as a LE Sniper Rifle. We kind of got attached.
The second isn't a real rifle but a Mann Device, used by the army to test 5.56 Ammo, and that's pretty much all its good for.
I picked up a Ruger American Predator in in 6.5 CM. I'm quite impressed with this rifle so if I was going to get another 223 bolt gun it would be the Predator, hands down.
