The costs for a rifle can range from $300+ for used Thompson to $1,000+ for a new. I bought my Pedersoli through Cabelas for $600 a couple of years ago. You can also go the Kit route if you’re handy. The cost of powder is about $36 a pound from Duncans, balls are $18 per 100, caps are $7 per 100. Patch material is from JoAnn’s fabric. Then you’ll need a few other things like a short starter, range rod, anod a couple of other small things. The cost per shot is around 60 cents. So it’s a lot cheaper than center fire and a whole lot slower.
I can give you more info if you’re interested PM me, happy to talk.
