I have a Giraud trimmer and it works great on my .308 and .223 brass. The 6br is a different story, I set up the trimmer to trim to a certain lenght and then try a different piece of brass and it will trim .010-.030 more off. The brass also seems to get stuck in the case holder. I spoke with Dougs wife and she said to send in a couple of pieces of fired brass along with the case holder and he could open it up. Well I tried to set up the trimmer for my 6.5x47 and I have the same problem. Is this common for the case holders to be recut to fit brass.
