No fire forming just trim 6mm Hagar, size and load and shoot. Might pick up .5 gr of 1 gr the improvement of the NXS. Less case neck turning in future with 40 degree shoulder. Might take a bit more pressure.
Would it have feeding issue, I don’t know.
The developments with 6mm bra with target crowd is causing a quite a stir. Instead of 6mm br blown out to dasher or brx, etc. and all the case forming work. They just took a 6mm br case and ackley improved it to 40 degree shoulder and removed any body taper they could. This “new” cartridge design is 60-100fps slower but is setting a lot of records. Easy to tune they say. Less work to find good load.
The 6mm bra developments sure are interesting.
No what needs to happen is we need to have. The 6bra case or even the dasher with plug and play parts readily available for consumers. It’s a short case so it should accommodate heavy or light bullets. It also has the compacity to make it compete with a 22-250 on equal terms. Yes it’s beendone and yeah some say it works ok in a standard ar 15, but others complain the bolt and barrel extension is too thin. Haven’t heard of one blowing up yet though
I know of some AR's using a 473 bolt that came unglued. They were not pretty. Not my idea of just running a reamer blithely and loading to the nuts.
You're pretty talented Steve. Start writing checks and make it happen instead of continually lamenting what you think is perfect. Fish; cut bait or get back on the dock.

They make the wssm work in an ar 15, a .473 case should be easy, I think ar performance, does them. But only in limited amounts and I don’t know what people do about mags, again plug and play parts aren’t really there. I do support all the wildcats like this nxs etc. 223 is boring other stuff is better.
