Most accurate rifle I've ever owned, or shot, is my Savage 12FV in .243. I recently bought another 12FV in .223 for my son. His is not broke in yet, but it is the second most accurate gun I've ever shot. I think in time they will be on-par with each other, and that is FAR ahead of any Remington, Winchester, or Browning that I have to date. My Browning A-bolts, and X-bolt would be second in out of the box accuracy.
My son's .223 with range brass, mixed head stamp, and using a powder drop instead of actually weighing the charges put 8 shots in a row in a group that a quarter would cover. This was at 100 yards, using a CHEAP Pentax scope, and I was not letting the barrel cool between shots-I was just ripping them as quickly as I could. At last count I own 7 Savages, and they represent the smallest number of any manufacturer in my collection. But they are all the most recent guns I have bought.
How do you think I voted?
