There are several makers that produce fine accurate rifles. I own a Savage Model 12 FSSV that is sub half MOA on a bad day. I own a CZ 527 American in .221 Rem fireball that is beyond a tack driver, I am sure one in .223 Rem would be just as great. Remington makes several platforms. The VTR series are good as well. I was torn between the Remington, and the Savage. I do not regret getting the Savage. I am sure I would not have regretted it if I had purchased the Remington.
In the end pick the one you like the most. Truth be told they are all accurate, in fact more so than 98% of the people that own them. I am man enough to admit being that 98%.
