Who's shooting and reloading for this cartridge? How long does your reformed 223/556 brass last? Which brash to you use to reform to 300blk? And lastly what kind of accuracy do you squeeze out of it?

You should be able to get 4-6 loadings out of it IF you aneal the necks every 2nd or 3rd loading. I am about to gear up to make a batch of 3000 pieces if there is any interest

Ive got 6 reloads on 1x fired LC brass with pretty hot loads. The primer pockets are a little loose but I'm not getting any gas leakage around the primer.

I have been using LC brass for mine. I have only shot one round through them, so not sure on life. But it should be comprable to other rifle brass. I think 5 or 6 time for sure. I do think I want to trim the brass before loading each time though.

Careful what brass you reform lc is good always but there is some 223 and 5.56 brass that has thicker case walls and will get jammed in the chamber (I found out the hard way) pcc is one of those. It was bad enough were just dropping the round in the camber to check fit with no bolt it would stick and it took a alot to get it out.

As in what brass is best or what kind of accuracy are we getting period? Most of my loads are in the 1-1.5" range on a dead calm day. Im sure it could be better but Im not looking for uber precision out of this gun and I don't stretch it out much so I haven't pursued accuracy any further. My Noveske barrel likes for the bullets to be pushed hard. I only use H110 and under M80 pulls I run 17.6, 125s I run 19 and 110s I run 20. Those are all pretty hot so work your way up but they stack in pretty well. Below is my range notes for my finalized loads

As with all reloading information use at your own risk.
