Not necessarily just to be the contrarian, but I've always though that the semi-"rare" TC, 56 cal smooth-bore flintlock would do that trick.
You effectively have a 28 gauge shotgun, independent from PRIMERS, and a significantly-wide round-ball gun, independent from primers, and you could hunt small game with ball or shot and big(ger) game (closer) with ball. It's PERFECT! We don't need any other guns!
While a .410" slug might not carry a lot of authority, a 56 caliber ball certainly does - out just past 100 yards in a RIFLED gun, but the smooth bore may choke a bit on that. It would also effectively be a cylinder-bore if using shot, so there are lots of heavy compromises trying to roll it all into one. SHOT out of a RIFLED barrel makes a DONUT that shoots around the target, and the greater the range, the more ineffectual the pattern.
This is one that wouldn't be very good at EITHER and the compromise isn't worth it - you're hobbled in either situation. A regular shotgun can be a really good shotgun and passably good with slugs. Anything with rifling is going to make shot useless.
So, I can't support MY idea any better than I can YOUR (
@jordanka16 ) idea without buying the Renegade and trying it. Honestly, I think either gun would be a genuine HOOT and somewhat effective at what you wish to achieve.
I think the idea is absolutely worthy of the mental exercise, but I also think that the "exercise" is the only positive outcome. If a fella wants a lever-action 410, and wants to experiment, said fella should just DO that and not try to make it make sense. SOME viable and valuable information will come of it and there will be some element of usefulness, but enough to justify or rationalize the experiment.
Experiment for the sake of experimentation and don't listen to people like me. If it sounds fun, but you don't foresee a meaningful payoff that justifies the experiment, then just do it for the sake of the fun of it. If others think it's stupid, do it anyway, if that's what you want to do. Any one of us who HAVEN'T done it, haven't done it for a reason. Maybe everyone else's hypotheses are wrong?
You could do anything needs doing with a 22 LR;
You could do anything needs doing with a 12 gauge pump;
You could do anything needs doing with a 30-06;
You could do anything needs doing with a 357 Mag;
You could do anything needs doing with a stick and a rock.......
I'd be interested in someone reporting how the 410 lever-action fares at survival/subsistence-hunting/whatever else from someone who's DONE it. Yes, I'm trying to get YOU to spend the time and the money to assess the viability of the gun.
I DO appreciate that you can omit the qualifier of fending off hordes of zombies. I think like you think in that way - I think - a ONE subsistence gun to "get you through." There have been a lot of them - 32-20, 44-40 and 30-30 "homestead guns," grandad's 22 or Model 12, etc. I'm genuinely curious about what you (
@jordanka16 ) are curious about. It's an intriguing idea.
Never mind what the rest of us think - get one and you KNOW you have a viable 410 shotgun. We all KNOW the 420 shotgun can get small game IF we're on OUR game, but what will it do with .410" BULLETS at 50 or a hundred yards? Can you even HIT something at those distances? OOH! Round-ball small game loads! But then, why not just use a shotshello for small game?
@jordanka16 , you just opened a can of worms!
I think it's a neat idea and SOMEONE (
@jordanka16 ) needs to DO this.
