6mm arc build

[rdog]

Welcome to the forum!
And good luck on the build, keep us posted.
How long is the barrel.
I did a few cases of 6.5 to 6Arc to see how it went, couple of other guys have converted more than I did.
I got a trimmer that goes onto my drill, trim them then resize down to 6 Arc, chamfer.

I have a Lyman drill powered trimmer for that job 6Arc brass is all sold out in Aust.
the bbl is 23 inch.

Suspect your barrel will be threaded for a Moderator? What barrel length did you settle on?

Only down side to the 1 in 9 twist barrel in your case is factory ammo is not likely to shoot well. Would not be surprised if the longer factory bullets currently available shoot so poor that you may wish to pull those bullets & move on to shorter OAL bullet options.
Not sure if you have access to the PPU 100 grain bullets. If you do these should be short enough that they would still shoot well from the 1 in 9 twist barrel. Over on this side of the pond Powder valley is one of our suppliers for the PPU bullets.

I understand that factory ammo may not stableise i a 1-9 twist, i brought them for the brass Have plenty of 6 mm bullets on hand as i shoot a 243 Win & 240
