One of my favorite subjects, and as I see from many comments, as often as not the "customers" (youth) are being blamed for not not being "customers." Same on many forums.
And yes, the future is in youth, and if we want to see our sports survive, the industry had better start treating people as customers, especially teens.
If your school is like most, it has extreme anti-gun policies, perhaps zero tolerance for even clothing or jewelry that depicts firearms. Starting or participating in shooting clubs is typically not an option today in school.
I am a multidiscipline shooter, and some organizations are better than others at getting everyone of every flavor, shape, age, and size involved, and having fun.
The CMP is a model for inclusion. Lots of younger people participate. Lots.
I suggest a SAFS to get your feet wet. No investment, just a match fee, and you'll meet people.
Not much ml (but Talladega actually has some), but many other opportunities to find like minded people your age are at these large venues.
Wear ml t-shirts and/or sticker up gun cases, etc, with muzzle loading stuff at any gun/shooting event or gathering and conversations will soon follow.
