Here you go..... Be sure to carefully read the part about turning the necks down. You must know your chamber dimensions to do it safely.

Forming 6mm AI brass

I made a bunch of 6mm AI brass from 7x57 RWS brass. Good stuff. Far superior to the Remmy brass I used before.

"far superior" is a pretty strong phrase. I shot a 244 Ackley in 1000 yard Benchrest for about 10 years and used nothing but WW bulk brass. My best buddy used R-P bulk. Both of us won our fair share of fake-wood trophies so it must not have been that bad.

The Internet is a wonderful thing but I think the easy dissemination of advice is one of it's drawbacks. What used to work, still does, but you would not know it from a lot of the "expert" advice bandied about.

Buy a high quality barrel, chamber it closely, discard any obviously bad cases, choose a good bullet and the correct powder, and a 244 AI will shoot as well or better than most.

And watch the flags.

Over the years we've sure dispatched more then a few p-dogs out past 600yds using both RP & WW brass and we always shot our fire form loads while doing it.

Ray,

You are totally correct in your statement. I had great success with RP brass in my 6AI once I culled 10% during brass prep. My issue with RP brass was that I wrecked it after only a few firings with top end loads. Primer pockets were so lose after 3-4 firings it wasn't usable. I probably push the upper limits trying to drive bullets faster than most. My RWS brass is far superior in terms of toughness. I have +15 reloads on some of it and still going strong. That is my experience. I use WW and RP brass in my std 6Remmy all the time. If I wreck it, I through it away no big deal. However, by the time I size down, turn necks, anneal, and prep the 6AI brass, I prefer to see a few more firings in a life cycle.

I certainly wasn't referring to you when I made that comment about expert advice being bandied about. You are a shooter with experience, while the kind of advice I was referring to is coming from the experts who seldom pull a trigger. I'm sure you see as much of it as I do.

You are right about the RWS brass being harder and lasting longer. That's why I made the comment about chambering the barrel closely. With a tight butt chamber, the WW or R-P brass should last as long as the barrel.

I have not tried 6mm AI but have owned several .244 and 6mm Remington rifles. I currently have two 6mm Remingtons, a 788 with 25.5" H-S Precision barrel and a 40-X with 30" Krieger, both 9".

My experience is that the Winchester brass is better than Remington and, with annealing every three firings, will go 12-15 firings. My loads are fairly stiff but within SAAMI spec, between 55 and 60 ksi.

I use Lapua brass in .223, 6mm BR, .308, 7.5X55 and .30-'06. If rumors and pictures are true, soon .22-250. Lapua is overall the best brass currently made. Sadly, the 6mm Remington is not very popular these days and Lapua is unlikely to accommodate me in that caliber.
