Re: XBR with 105's
I don't know what your shooting, I assume a 6br, I had pretty good results with my 6brx with 32.4 grains of 8208 and 104's and 105's but start low and work up in small amounts as pressure signs come on fast, everything working good one minute and bolt is locked up the next, worse then 4895 for that, was showing good promise though, I tried it yesterday in very windy conditions and was in the two's and three's at 100 yds but had a flyer every once in a while, don't know if it was the wind, me or powder, definitely worth re checking for a back up if I run out of 4895, if you are running a straight 6br, I imagine your about at the upper limit with that load.

Re: XBR with 105's
Got a little experience with this setup. I think charge weights depend a lot on how fast your lot of powder is. I'm currently running 29.5gr 105 hybrid in 6br.
I have tested all the way up to 30.5 without pressure problems.
Tested a different 6br barrel and Lot of XBR last summer, 29.3gr shot some really small 600 yard groups but was a little on hot side.
