I have a questions for all of you gents shooting the heavy bullets out of the 6.5x47, what have you found as your go to powder? I am currently shooting the 123 scenars and 130 VLD's using Varget/RL-15 and CCI#450's, but would like to give the 139/140 class of bullets a go.

I have heard mixed things about shooting the 139/140 class of bullets, but would like to give it a try. I was contemplating using something like N550 with CCI#450's. Is this a good starting point, or should I look at another powder?

Gun Specs:
Savage 111 action, Criterion 28" SS Match barrel

Thanks for any data or info you guys have.
