6mm ARC Help

[fwood]

I am trying to work up an accurate load for the 6mm ARC in a gas gun, 18 inch barrel. I have been using lever, I have gone from 29.5 to 31 grains my smallest groups were at 30.5 and 31 about 1.75 inches. I have been working the seating depth in and out and not getting any better. Anyone have any data out there for the 90 grain ballistic tip or AccuBond that is shooting well. I have Varget and lever. thanks in advance any info would be helpful. Yes I have the horned book. If you need a great load for 75 grain, 31 grains of lever

Bbl twist?

Moreover what was your starting depth? Sometimes we get ahead of ourselves and start seating what we "think" will be good versus keeping it simple ahd starting at the listed COAL for that recipe in published data.

We've all been there.

Two questions though.
Twist and your start depth?
