Why is the case on Monarch 7.62x39 ammo, a green sorta color? Is this not brass? And why do they put the red water proof gunk on it?
It is green due to the lacquer or polymer coating on it to keep the steel from rusting and aid in cycling. It is not brass, it is steel. The waterproof gunk is done to most military ammo for storage or hard use conditions(more or less).
stupid question maybe......why can't you reload steel?
You can. It needs to be boxer primed then you treat it like any other casing.
2) I think your dies would last about 3 minutes
3) Brass is rather supple. You might not be able to develop enough force with the std 14" throw arm on your press to cold work steel.
Your dies will last just as long as with brass. It takes no more force than with brass. The problem is that the dies are made to the dimensions that will allow the correct amount of "springback" to get it to the desired size. Steel does not "springback" the same as brass.
Makes sense......it's just physics huh?......or metallurgy I guess.
Too early to think about physics.
It's definitely metallurgy though.
brass better suited to both reloading and firing than steel, and steel requiring so much more force to resize, and being therefore harder on both you and your equipment, the question is WHY anyone would bother trying to do so. Some people, I guess, feel compelled to try anything that is reported to be more difficult than necessary.
Brass is better suited, no doubt for reloadability. Again, steel requires no more force to resize, and is not harder on you or your stuff. It is a mild steel and will not harm your dies.
I have not tried loading steel 7.62x39, not even sure if it is boxer or berdan, but I have loaded a lot of 223 steel mixed in with brass in a Loadmaster and also a single stage with no noticed difference in feel. Dies still work, press still works, operator may have issues, but it's all good. You will not get as many loadings out of steel cases, but 2 or 3 then chunk them and you'll be fine. I am not advocating anyone load steel casings, just police them up and pm me for an address for disposal.
