Have you checked the 6.8 Forum? Theres a couple of guys on that forum that are using 130 gr bullets in 6.8 AR but loading longer that mag length (by cutting out the front of the mag) and even cutting grooves into the front AR's magwell. I did recently read where so people were trying 130 gr Fusion pulls on deer. But 130 seems a little heavy for the 6.8 and the case capacity. 120 gr or lower works well. I have a bunch of 130 gr, but I use them for my 270AR.
