IMR XBR 8028 Where to start?

[hottshott526]

Hello everyone,

I would like to try some XBR in a 6XC. What would be a safe starting charge for 70gr SMK's, and maybe 107 SMK's also.

Using Norma brass, CCI BR-2 in a T2K.

I know this powder is faster than H-4350, which is the recommended powder, and may not work but thought I would try it out just to see.

Thanks and good shooting,
Brian
