Whats the concensus on IMR 8208 with this combo?
Thanks

A friend of mine was using xbr in his 6x47 Lapua the other day and getting pretty good results wit the 107 smk. However, he was getting better velocities and accuracy with RL17 and IMR4007ssc. WIth XBR, the case was not nearly full and would have probably been better with 95 grain bullets.
Now in a 6br, most folks use RL15 or Varget with the 107 bullets. My two 6br improveds shoot these powders best with even the 95 grain bullets. Seeing as how XBR is a little faster burning than Varget (more like H4895 rate), it could probably work fine but the load densities would have to be less.
It might really make 87 grain vmax hum out of the standard 6br.

Ill know by this weekend
how it works with the 107 MKs, I know it works great with 108 bergers(better accuracy and more velocity). I was able to get 50 more fps than with Varget around 3000fps is where I found the most accuracy with 30.9 gr. There are higher nodes but I got flyers with them.
