Brass is the only way to go DG!
I reload brass shells with 00 for my war2 trench guns. I use smokeless and okay, okay, they are more like trap loads in recoil than the real deal.
Anyone who has not heard the 'CHING!' that a brass hull makes when you eject it out of a pump is missing out on something. It is labor intensive to load them, but the cool factor is worth it.
I have had to pull some down. I just dig out the components. I have never heard of a struck primer going off much later. Just wear eye protection when you deprime.
