Build#6/18" 6.8 and some load data

[jh308]

I'm the only person I know shooting this round, so a fellow 6.8 shooter locally would be great to bounce things off of.

I see that. I have a LWRC, but looking into either a XT or MK68 upper from AR Performance, so all your work has helped me quite a bit.
Did you end up with the flat wire buffer spring? I was looking into one as well.
I will try and take you up on your offer, I think I would learn a lot. Need more 68 shooters.

While I (IMO) purchased a very accurate barrel, I wished that I would have paid a little more $ and bought one of the MK68 bbl's. I think they would be a 100fps faster AND still very accurate. If I keep going at this rate, I'll have this barrel shot up soon enough tho.

I haven't tried the spring yet. I just swapped the steel weights for tungsten in my buffer so far. The spring is next on my list. i would probably learn just as much, and yes we need more 68 shooters. I try to get a couple people to play w/my SBR every time I'm at the range if I see them eyeing it. I gave a couple pieces of brass out today, so hopefully we can slowly get a couple more at a time...

Good luck w/your build.

I broke down and orderd some PRI mags finally awhle back. Increasing the COAL of the accubonds to 2.295" from 2.280" seemed to do the trick. I had much better accuracy than my previous attempts and I didn't have nearly as many pressure signs.

110gr Accubonds:

RE10x----Avg-----ES-----Group
28.1-----2582-----14----0.766"
28.4-----2610-----11----1.061"
28.7-----2638-----27----0.846" 3/5 had Ejector swipes
29.0-----2652-----30----0.968"

H322-----AVG-----ES-----Group
28.1-----2495-----21-----0.921"
28.4-----2518-----12-----1.124"
28.7-----2539-----17-----1.028"
29.0-----2594-----27-----0.724" Ejector Swipes

I also loaded up some 130gr Nosler BT's @ 2.285" COAL w/RE10x to compare w/the H322 & BLC-2 loads that I had already tried. These and the 115SMK's are easily the most accurate bullets out of this rifle.

RE10x----AVG-----ES-----Group
26.8-----2411-----25-----0.640"
27.1-----2429-----24-----0.932"
27.4-----2444-----27-----0.564"
27.7-----2468-----19-----0.854" 3/5 had Ejector swipes
28.0-----2481-----23-----0.789"

Don't forget about me! I'll be picking up my 6.8 XT from ARPerformance sometime this weekend.

Haven't forgotten. I'm still trying to figure out when I can take that trip I was telling you about. I'll PM you when I get that done.
