anyone shooting H4350 in 6br?

It seems like it might do well in the 6br with heavy bullets, anyone tried it?
Thanks,
Joe

I have shot several pounds of RL17 in 6BR, mostly with Sierra 107MK. My top loads are from 98% to 100% case capacity. H4350 is slower and less dense than RL17 and it does not look like you could get enough in the case to reach pressure. RL17 is probably about as slow as you want to go in 6BR. I shoot a 30" barrel and can take some advantage of greater powder progressivity.

It is the first powder I tried as I have lots of it, and use it in my other calibers. I couldnt get rid of verticle (big velocity spread). Once I switched to AR2208 (Varget), the accuracy came back in a big way. The load was too compressed with H4350, maybe this affected velocity spread.

Thanks guys. I have a lot of H4350 that works great with my 7-08 I was hoping to recycle.
