6mm Arc bolt gun with 95 lrx, which temp stable powder?

[rustvendor]

Hornady data only lists varget for temp stable, barnes lists zero temp stable powders, Sierra lists 8208 which could be promising. 22 inch howa mini, would be nice to get 2900 fps at that's over 2k fps to 450 yards. 2850 would be over 2k to 420 yards so that's fine too but faster is always better for copper. There's a ton of powders that should work that don't have any data so has anyone used any of these on 90-95 grain bullets in 6 arc? Staball match, h4895, n130, n140, n150 or ? Ive run most of these in GRT with mixed results, they don't really seem to line up with what i've seen others loading at but who knows.

Define temp stable within your parameters?

I think temp stability, while it can matter, is also a bit overblown.

Varget is never a bad choice when applicable.

VV has gas gun data for the 95 lrx with N540 and N550 as well as several 100 series powders, should be able to get something started from there.

I have good luck with Varget using the 95gr LRX. It is a little compressed, but no need for a dropper tube.

I just worked up until I saw pressure signs, the dropped down a half of a grain. It’s probably still a little hot, but it shoots so well I haven’t messed with it.
