Ordered up a barrel in 6x6.8 from BHW. I went ahead and got the 6.8 bolt they offer as well. I've been contemplating another build for years. Like alot of people I bought a 2nd AR-15 lower prior to the 2008 election. I still have yet to build that lower. Until now I have not been able to decide what I wanted to build. First it was going to be a beowulf, then grendel, back to beowulf, then a blackout, and on and on and on. Just when I thought I had my mind made up, 25-45, I somehow stumbled onto the 6.8 variants. "Oh great, something else for me to ponder". I wanted something that could hit harder than the .223. That I knew. I finally "settled" on the 6x6.8 simply because of the rather large bullet selection when compared to the 6.5x6.8. Now to figure out the rest of the build. Might be another 8 years.
Got the shipping notification yesterday. Yee haw. Just ordered up all the reloading materials too. This is going to be a fun summer. I also had my Remington 700 long action re-barreled to 280 ackley and got that back recently. Two loads to work up this summer. I'm like a kid in a candy store.
