Who's running this cal, doing a barrel swap from 6br to 6 x 47 1:8 twist and would like to save some time finding loads, what powders have you had success with out of this round?
6 x 47 lapua
- Thread starter JTCWCES
- Start date
I'm using 41.3 H4350 and a 105/107 grain target bullet and CCI 450 primers. 8 twist rifle, velocity around 3200fps. have had excellent results with Berger, Hornady, Nosler, and Sierra Boolitz. My current barrel is a little faster than the first one. Here's what others are running:

H4350 and Reloder 17 are the two that I have tried.
I get 3050 FPS with RL17 / Hornady 105 BTHP bullets out of a 26" Broughton barrel. One grain hotter and I have primers starting to really pucker due to the large firing pin in my gun.

These are safe in my gun.

Has anyone tried 4831sc? Quickload show's that about ideal with 105s. Along with RL19 and some of the slower powders. BTW, max pressure for max pressure I'm showing the same velocity for H4350 and 4831c
