You got it - I just found out today that Niagara Gun Range does allow jacketed but I have yet to find a club with an indoor range that does...I'm gonna guess your talking about the clubs in the Buffalo area? I don't know of any that let you use jacketed ammo or any of the alternatives that were listed. You could go with the drop in barrel or just shoot lead. I have a 22 and 23, 1000's of roads lead though them and no problems.
In a word, FUDDS. Most of the ranges here are old, the old guys think, and them may be right, they may not be, think jacketed ammo and even plated ammo will damage the back stops. Its not a regulation, its a club rule, I won't pay the extra $20 at my club to use the indoor beasue of this.Never heard of that regulation - Does anyone know why?
