Makes me feel a little strange to have the need to ask. I am on a small SS and with the prices of gas and everything going up well! I am in need of some 284, 6.5 x 284 brass to form 450 Bushmaster out of. Maybe someone has some in there trash bin with split necks? You might be asking why bother, it is because I have around 1000 Large Rifle primers and maybe a couple of 100 sr primers. Thought maybe making a few pieces of brass to use with large rifle primers might hold me till primers come back and maybe prices go down. Thanks everyone for looking.
