Proof Carbon Fiber 20" Preliminary Results

[Azgeek]

Initial 100 yd testing Still need to break in barrel and bring the correct bi-pod next time! Have about 40 round through it.

Nice! I have one sitting here for a build. I'm curious what your hot strings will look like.

It was an awful day at the range. After finding out my son forgot to load the box with my cleaning stuff and my bi-pod, the first two groups were shot off a block of wood and shooting bag. Had an M4 grip/bipod combo that I use for the other three groups. Too many distractions and problems, plus I had kids around. Proper testing will take place next week. If I do my part, I see no reason why this barrel will not shoot .5/.6" groups after fully broken in. The barrel never got hot. Really weird! Zero copper fouling found during its first two cleanings.

The only thing that will stop a Proof CF barrel from shooting inside 1\2 MOA is the shooter. I do it all the time

The thermal properties are really something you have to see firsthand to believe

Now if someone will come out with a CF supressor...not that any of us could afford it.

Looking forward to your next report. A CF barrel will be my next replacement...period.

Azgeek...you didn't happen to weigh that barrel before you installed it, did you? A quick internet search doesn't turn up a weight for me and their website is a little vague.

[Azgeek]

Yes sir did. 2.2 pounds.

Did you chrony them 8208 and 120 SMK loads by chance?

[Azgeek]

No I did not chrono. Too many other challenges that day. I have not shot the SMK 120's in years, but I would expect this load to come in at in at about 2510 fps. Be happy to get you a number this week on my next outing. Taking Friday off for just this reason.
