Imagine the time it will take for a Match Director to go through a dozen people's ammo to ensure they aren't shooting bi-metal bullets vs non bimetal steel case. Quite frankly, if you are one that believes this is irrelevant time spent so you can come out and shoot garbage ammo, you are wrong. Almost every minute of my time before a match is already spent setting the match up. The ricochet and fragmenting danger of the bi-metal bullets alone is reason to not allow it. At my match, I have shot steel as close as 50 yds. I know my matches attendance is down now, but I even started a 22LR and PCC divisions and I get only one or two max at a match. It's quite frankly not worth the effort for the extra steel set up time and I'm going to stop having those divisions. There have been ways around the ammo cost instead of allowing annoying destructive and dangerous ammo and nobody is taking the opportunity. So, no steel case at my match. If you do it at my or Hosers match when not allowed, there is consequences.
