Yup. Had a LBC reamer but never got round to chamber a barrel with it, the 6PPC was going so well that I ended up selling the reamer to a mate.
Ordered a Howa in 6ARC......
When are the Howa 6ARC's due to our shores?Quote:

How much less capacity does the ARC have?
Certainly a cheaper and easier way of getting very similar cartridge.
Will let you know as soon as I find out mate. Last news was 2022
I was getting around 3050 with 87gr vmax when fireforming 6mmBR brass to 6mmBRA. 30.8gr of powder out of a 24" barrel.Quote:

It seems really good performance for the amount of powder burnt.
What do you use your 6mm BRA for?
I built it for varminting but have used it for a couple of matches recently. Got a heavy barrel that I'm chambering in BRA too which will be primarily for match shooting https://uploads.tapatalk-cdn.com/202...75b286085a.jpg

New 6mm barrel from Truefile (have a cheap 7.62x39 if you want a new one) wanted their deep valute fluting to help cooling as this rifle fires lots of rounds (45 goats last weekend). The 87gn bullets perfect for bigger animals deer and 75gn perfect for goats.Quote:

Ive seen what 87gr Vmaxs from a short barreled 243 do to goats, very impressive.
Sweet rig! Who fitted the barrel?Quote:

GWH.....bad news. Yust got the very sad news that Howa canned the 6mm ARC idea.
6mm BRA it is then.
Ballistically the same as a 6mm-204, but in a short powder column. I'm sure that 75gr load is mild as that's what I get with my 6x45.Quote:

Yes Grant has a 6mmARC reamer, I got a 1x10 twist as didn't want to shoot the heavier bullets. The 75gn vmax are very accurate and most effective with CFE 223.Quote:

Well that's no bloody good. I was hoping to acquire one down the line a bit ��Quote:
