So, I do see that steel is somewhat cheaper regarding 9mm and 5.56. Is brass better for the firearm or is that hearsay?? I have heard that steel can really gum up your rifle or pistol, but I have also heard it's no big deal and fine for training. Would you guys mind chiming in with your experience and help me get some education? I have only run steel through my AR some months ago because it was given to me and it seemed to perform just fine, but have only run brass since then. I have never run steel through my Glock. I am pretty good about cleaning my weapons, so if it's just a matter of staying on top of it, I can do that, but not sure it's worth the cost savings in the long run. I mean 2-3 cents less per round doesn't seem like a big deal, but 1000 rounds per month can warrant savings where you can, right? Anyways, appreciate any input you guys have.
