If accuracy is your goal , let the smith do it all . Chances are the pre chambered barrels chamber will not be exactly what your smith has to finish ream . I've seen many with 2 dia necks .What steps need to be completed to install a “pre-chambered” barrel onto a Rem 700 action? Does the “pre-chambered” configuration save a smith time compared to shortening/rechambering an existing overbore (.243) barrel with extensive throat erosion?
What exactly do you mean by prechambered?
If you mean Remage style these barrels use a barrel nut that you would need to buy also. These would save alot of time. Only takes minutes to swap them.
http://criterionbarrels.com/media/newsIt is not an accident for a pre-fit to shoot well. I have a Criterion on my Savage that shoots very well. If you search a bit you will find there are several national records held by shooters using Criterion barrels.[/Q make believers out of all the doubting Thomases.
Here's a link that shows 3 winners!
If these guys want to be recognized as having good stuff, they need to get guys like Wayne Campbell and Eric Cortina to use them and win with them. Three guys that won something isn't a very large sample.
It may be hard to understand and appreciate but I know several hundred shooters that use for the most part BAT actions on their match rifles. These actions consistently headspace within a few thou. of each other, so you could go to a short range br match and unscrew the barrel off of competitor A's rifle and screw it on competitor Z's rifle and it would very likely headspace correctly. But none of these guys uses a prechambered barrel from one of any of the outfits that sell them.
