I have a quantity of 444 Marlin brass that have split case necks. Much of this brass has never been fired and the remainder is once fired. The necks split because I failed to anneal them after forming. If anyone is interested in these, I will get a count to let you know how many there are. These can be formed into 30 Bellm. I just ask that you pay the postage for a small flat rate box, the brass is free.
