Why isn’t Varget ideal for 6BRA?

[Rich S]

I've been told that Varget doesn’t work well in 6BRA and that I need to use H4895 instead — but I’m struggling to understand why.

The 6BRA case capacity is right between 6BR and 6 Dasher, both of which are known to run great with Varget. Then as you move up in case size to something like the 6GT, people often use Varget or even H4350. And for larger 6mm cartridges like 6 Creedmoor, H4350 is standard.

So why does the 6BRA supposedly not like Varget, despite sitting in the middle of a range where Varget is often ideal?

Look up the equipment list for 2024 IBS and Freedom 600 yd nationals and Vapor Trail Rendezvous. There is at least 1 of the top competitors using Varget in a BRA very successfully. It may come down to what velocity your chasing.

I have yet to find a barrel that IMR 4064 didn’t perform great in. Big kernels and slight temperature/conditions sensitivity are the only “downsides” but it’s closer to a temp stable powder than it is to the unstable stuff like ball powders. It’s a shame it’s so expensive because that basically obsoleted it for me.

Got to love IMR 4064. From heavy bullets in 223 to light bullets for the 375-338 and everything in between. Clean burning also.
