10mm mag brass cut to 10mm auto.

Has anyone done it? Sounds like it has a better web. Being starline is not taking orders in 10mm reg brass I see they have the mag in stock. Could cut down. I would more or less only cut down for hunting loads. If its stronger it might be good for it.

I think case volume may be reduced due to the thicker web, but im not sure

That should not be a problem. Still have some room in some. And anything that is compressed will just have to rework it. I think.a stronger 10mm auto case is the way to go. I must admit cutting down a few hundred will not be fun.

Interesting project. Please keep us posted. It would be interesting to see what the internal volume differences will be.

If it works well we will have to get starline to start making some 10mm mag short brass. Lol.

It won't work, without some significant accommodations.

First, the cases aren't that different, and working pressures of the round are about the same, so the case web isn't a serious consideration. One advantage may be that most Mag cases have small pistol primer pockets.

However, cutting brass defies their design. Case walls, compared to the case mouth, are thicker and usually more brittle (not annealed, if the mouths are routinely annealed). This causes a problem when fitting bullets. The thicker case wall will either have to be reamed to accommodate the bullet, and maintain bullet diameter and seated [new] case mouth outside diameter. Unless you do something about it, they won't fit into the chambers. It is just not worth it under normal conditions. If I had no other source of brass, I might be inclined to make it work, some way.
