I've read several times before on HKPro about the horrors of steel-cased ammo, along with other stories that Google turns up and the posters that avoid all steel in the zinc-plated steel ammo thread here, but I've also known a lot of people that shoot it rather exclusively, and a lot of the forums (e.g., HKPro) where the stories show up aren't very turned on. While my switch from .45 to 9mm has given me substantial savings on the ammo side, I am curious as to whether or not it would be a good idea to feed my only handgun (P30LS) steel (lacquer-coated, stuff like Brown Bear) exclusively for training? Thanks.
