I agree, I shoot a variety of 6mms SLR, BRX, Fat Rat. If you can't get 108s to shoot then you have a problem elsewhere. It could be your loading technique or the barrel just isn't happy. Something I found on one of my SLRs is when I hung a can off of the barrel, it tightened right up... crazy accurate... it rivaled my BRX. So I bought a tuner for it and wow. Now keep in mind this was a very consistent shooting rifle, but just not a one holer. One other thing that I have seen for a number of years with hybrids. I couldn't get them happy at 100. My 100 yard groups were almost identical to my 200 yard groups (yeah, I've read all the data that say it just can't happen). I just figured I was doing something goofy. The hybrids liked my 7.5 barrels better than the 8 too. 108s just don't care. I see we are shooting about the same speeds. My SLR has two nice nodes but I like the higher 3130ish node. Long story short... Try 108s for the giggles of it Test your hybrids at 200. If you live in the Northern Nevada (Reno) area and can't find any... just PM me and I'll give you a handful of 108s to try.
