Re: New 5r 700 vtr
If you want a nice 5r barrel, get one from a custom maker rather than Remy's production version. 5r is just an angle specification on the rifling. It is not inherently accurate by itself, it is only accurate if the barrel itself is well made. There are many more examples of super accurate standard barrels.
Shoot what you have first and see what you got. To give it a fair test you'll need a better stock and a good bedding job.
After you do that, some Fed GMM match ammo will show if the barrel you have is a keeper or not.
