Criterion barrels - excellent
Hey guys,
Just wanted to let you know what a fantastic product the Criterion barrels are that Herb on this forum sells.
I bought a Criterion 6.5mm, 1:8 twist barrel blank off Herb about 6 - 8 months ago, that I then had chambered in 6.5mm SAUM, and profiled / crowned and fitted to my Remington 700 action by Scott Trail of SSRNZ. Later, I had Gunworks Canterbury do a very nice job of fluting.
I have been out at the range for the last two weekends doing my barrel run in and load development. First I'd like to say that I wouldn't bother going through a very lengthy barrel break in process with these Criterion barrels. In my experience, run in for first 10 rounds (fired one, clean, fire second, clean etc for ten) , then just shoot as normal (and then maybe clean after the next 10 or 15 rounds, then just shoot as normal, with a good clean when the shooting is done for the day).
I found this barrel to have very little in the way of copper fouling and seriously after first running a good copper cleaner down the barrel (I use Shooters Choice) and letting it sit for a few minutes, it took just 4 patches and the barrel was perfectly clean.
These are the smallest 3 shot groups I have shot to date with my Criterion Barrel. Both are sub half MOA (one measures 0.458, the other 0.383, centre to centre measurements). (The two shots in the black at two o'clock were the last two rounds that I had left). As you can see, plenty of twist rate to stabilise the long 143gr Hornady ELD-X projectiles that I have 300 of and will be my bullet of choice in this rifle.

They have also been getting excellent reviews on the Internet on some of the internet sites such as www.6mmbr.com
Big thanks to Herb again for making such an excellent product available at a fantastic price. For a custom rifle on a small budget (well almost small), I can highly recommend these barrels to anyone.
