I am not much a brass collector, but I have alot of LC 44 brass I got as de-milled. So I guess they are not rare. As far as the steel case, they are a bit of a rarity, so keep them - but do NOT reload them. Steel was/is not reloadable.

The LC 56 is reloadable as is the LC67. I like the LC brass best - the most durable.

Just make sure you trim the brass to proper length before you reload it.

Hope this helps...
