What I think is an unbiased opinion.I started shooting my grandads muzzleloader [originals] at 12 I am now pushing 70. I can build [and have ] a round ball hawken that will take deer for me at 175 yds without any problem. So whats the big deal about a bit of range? The real advantage I see is less chance of a rifle being ruined by rust or corrosion and less effort to clean them. The biggest draw back that concerns me is that there is a lot less room for error in measuring powder when using smokeless designed for cartridge guns. Since most deer are taken a bow ranges any way I believe that anyone who believes that it gives them any advantage other than convenience under normal circumstances is wishful thinking.
There for I do not see any reason why they should be barred except prejudice even though I have not chosen to use one myself.
We need to help and support each other; if we do not hang together the antigun miniminds will have the chance to hang us individually. Lee
