Starting load with 1-12 6br

[Two Bears]

I am new to the 6br
Found myself a 15" Encore Bull barrel 6mm br. It is a 1-12 twist.
Where would be a good starting point with bullet and powder/charge?
Will be used from 100 to 300 yards, but mostly 100 yards.

Thanks in advance.

A good flat base custom bullet in the 65 to 68gr. range.

My 1:12 twist 6BR Improved shoots good with everything from 55s to 80s.

The 15 inch barrel will dictate the powder and bullet choice.

in my 6BR 12 twist, I shoot 80 grn Bart’s BT’s with 33.5 grns of Accurate 2495 out of a 26 inch barrel. That might be too slow of a powder for your short barrel. But I think the 80 grn would be the right bullet.

if you want, I could send you about 75 of the 80 grn Bart’s to try. That would be enough for you to see how well your barrel likes them.

One likes 30.5 of h4895 with rem 7 1/2 primers and Barts 80 bt.
The other one likes 30.5 of 8208 xbr with cci 450s and Barts 80 bt.

If it was me, I'd start at about 27 or 28 and work up from there.
What works for someone else doesn't mean it will work for you.

Sorry I didn't read the original question very well.
My loads are where my guns shoot the best, not starting loads at all.
I started load development at 28gr and worked up to where I'm at.

Thanks guys, it gives me a good starting point.
Now I need to find some brass.

Two Bears, what kind of freebore does your chamber have? This would dictate to some degree what bullet choices you would make.
