Need a good load for my 6mm br.

I would have to look it up to be sure but if I'm not mistaken, I'm shooting 31.5 grs. of the old AA2015BR powder with a 70gr. Nosler Ballistic Tip. This powder has been discontinued so you might try Hodgdon Varget which has been working very good in other guns.
By the way, my gun is an XP-100 from Remington's Custom shop. My load averages 3215fps. and prints in the low 3's at 100yds.

Big fan of 6mm, been thinking about a 6br lately, everyone seem so impressed with 6ppc but 6br seems a little more practical and just as accurate, at least as well as I can shoot...
