need 444 marlin cart.

You mean you're looking for .444 Marlin brass?
Seasonal only by Remington. Not being made by Hornady or Winchester. According to Midway.
Ammoseek.com lists a bunch of loaded ammo from assorted makers. That'd be your best bet.

Now that's forward thinking.

Sold my brass. I have RCBS dies I've been meaning to sell.

How many is a few? I have some new brass, not a lot, but some.
