10-4, I have the SAUM die and wanting to switch between 6.5 and 7 eventually.
I think it’s worth it to have adjustable shell holders whether it’s for having same cartridge rifles or not.

The dies do get expensive but a lot of the pieces can be used in their other dies as well.

LB, do you use SAC resizing dies for .223 Remington? I'm looking into them, and trying to decide on a neck/shoulder size and the decapping mandrel to match. I've been using Lapua brass for awhile but it's getting pretty beat up and I don't see more available. Might take the opportunity to switch up to all new brass at the same time. Any suggestions on a good brass, and based on it's loaded neck OD, a SAC size neck/shoulder and mandrel? I'm not annealing if that makes a difference.

I do have the sac 223 die and use it with a .222 expanding decapper. Bushing depends, but I size .004 under loaded diameter then the mandrel expands to .0025-.003 interference. I also anneal, so spring back is minimal. If I wasn’t I may size a bit more to account for it.

I’m spoiled now by sac dies and can’t go back, no doughnut, they size lower on most cases, and they make it so I only have to be pull the press once.

Only a few options for 223 brass, I have some Starline that I’m still learning. Adi is good stuff if you want to buy the loaded ammo to make it. Berger ammo is loaded in lapua so that’s a route too depending how much you need. In another thread I saw lapua was doing a run soon as well.

Spend the money on the expanding decapper and get the little wrench deal. Sac makes a good product.

Thanks! I'm putting in for the .2220 decapping mandrel. That seems to be the easy part. I think I'm on the fence between two bushings, but will go with the smaller of the two to be safe, and may try a size up later if/when Lapua comes back to retail.
