IMR 4007SSC Powder

Has anyone tried IMR 4007SSC in a 6mmBR? Just from the burn rate I thought it may be worth finding some info on it.

I'll be shooting some in my 6br within the month. I'll keep you posted on the results.

Somewhere in 6BR.com is load data for the 6br listing a 105 Lapua? behind 31.5 gr. of IMR 4007. No vel. data is given. I tested 4007 in my 6 mmBRX this past wkend. It was too slow. My max load was 34.5 gr. which yielded 3043 fps.31 in barrel. 34 gr yielded 2965 fps on avg. My max load showed pressure signs, ejector marks, and grouped poorly,1 in. 5 shots at 100 yds. I've concluded that this powder is too slow for the 6br/6brx case. I'm sticking with Varget and Reloader 15. Hope this helps.
