Great ss barrel in a great caliber, 6mm cm - Proof Research PR10 Stainless Steel Barrels

This is a really great barrel. I have it and it's a half MOA barrel or better when you do your part. Many veterans will swear by Proof Research barrels as well as myself. I've seen the reviews on other websites. I was getting about 3,020fps with Norma golden target match ammunition out of this barrel at about 5k ft elevation in moderate temperatures. I believe when i ran the numbers, you are still supersonic out to a mile with this thing which is unbelievable. I can't remember which of my 6.5CM rifles i compared it to... maybe it was the slower Tikka Tac A1 but essentially there was 10ft LESS drop at 1,000 yds with 6mm CM than there is with 6.5mm CM. There is also purportedly 20% less recoil. The recoil IS in fact noticeably less, which is a great thing. I took it out to North Springs shooting range in Price, UT and before my AR10 started having FTF and FTE issues i went 3 for 3 on the 10" gong at 1,003 yds. Last weekend i put a different rifle length AR10 stock instead of the carbine length with JP Silent Capture Spring i had been using and trying to make work. So with the new, rifle length lower and traditional buffer and spring, i didn't have any issues in 15 rds save the first rd fired didn't fully eject but that's likely because the rifle was dirty. After that, the other 14 rds fired flawlessly with a good ejection pattern of 3:30. I do have the JP adjustable gas block on the rifle. My barrel came with the gas tube (rifle plus 3") and yours should too. I've spoken with Proof directly and that's how they do it. I'm going back to the mountains to shoot this coming weekend with this rifle. If the new lower continues to enable the rifle to function smoothly, i will compete in PRS matches with this rifle or any other rifle match i can use it in.
This weekend i will try to complete the JP challenge at 800 and 1,000 yds which is to say fire three rounds at the silhouette before hearing the ding from the first impact. So, bang, bang, bang, ding, ding, ding. I plan on one upping 3 rounds to 4 and maybe even 5. I believe i can do it with this caliber and my set up with the brake i have on there. If i can at least get 4 shots off before hearing the first report, i will post it to my youtube channel, Shot On Christmas.
