New 6BR XP100!!

[Ammohouse]

My new 6BR!
Working on loads with 87 Vmax & 85 Sierra using Varget.
Started with 30grns now trying 30.5grns.
Varget load data is kinda all over the place.
I see folks using 30grns for 105s so I’m thinking I’m at the very bottom for 85s & 87s?
Tinkering is fun!
Next powder to try is 4350 & H335!

Might consider backing down a bit on the powder to a "lower node" and leave yourself some "wiggle room". You load at 70*, hit the range and it's 100*+.
You got a big enough hammer to beat the bolt open??
And who cares about the FPS if they're all going in the same hole.
And if it makes any difference, your brass will last longer too.

Around 30.5-31.0 of Varget is a good place to be in a 6BR with 85-90gr bullets. You might also try 8208, h4895 and n135 or n140 too. H4350 is a little too slow, especially in a short bbl but you might get it to shoot with some tinkering. I'm not sure about the h335 with those bullet weights. A 6BR is a great cartridge. It'll shoot just about anything good and it'll shoot what it likes, great.

Any other Varget load suggestions?

With 87gr Vmax, like @gunsandgunsmithing said, 30.5 - 31 with Varget is hard to beat.
