I have a .54 flint smoothrifle for hunting, and I depend on that gun for everything. This is not a gun for getting into a firefight where you need multiple shots quickly. (think AR-15) It is a hunting gun. If there was a possibilty of a gun battle, I would rather melt into the forest and disappear. My flintlock is no match for a high powered rifle with high capacity magazines.
I like the .54 as the ball is big enough for anything on the N.A. continent. The balls aren't overly heavy compared to something in the .69 to .75 range, meaning you can carry more of them. I chose the smoothrifle for the rear sight option for accuracy, yet still be able to shoot shot. Getting real BP is the biggest dilemma now, as very few places carry it. It has been in the past you could go to about any gun store and get Goex. Now .... you almost have to mail order it. With the rendevous all over the country, getting to one of those and acquiring a refill of real BP is about your best option... If you know where they are and can be there the dates they are held. I would not be against extending the life of your Real BP by using duplex loads .... !/2 real BP, and on top of that either Pyrodex, 777, or what ever substitute you can get. As for lead .... if you run out or run low, hopefully you are carrying with you a ball mould for your long gun. Every automobile in this country has wheel weights on the wheels. You can covertly strip some from cars, melt them down and make ball from them. Shooting wheel weight lead from smoothbores will work with little trouble.
If you need shot ... here again the smoothbore shines. If you need shot and acquire some modern shot shells, and it doesn't matter what caliber, you can cut open the end and dump that shot down the barrel of your gun.
In a survival situation ....you may need to slip into and out of cities and towns for supplies. Having a source of available cash will help. Eventually, if you are out in a survival situation long enough, you'll have to obtain your shooting resources from somewhere as you will run out. Clothing is another issue. Winter is coming on here in Ohio, and come December and January, it would be a real challenge to stay alive and well with just a couple of linen shirts and a matchcoat. A selection of modern clothes isn't much better. Carrying your needed winter clothes, shoes and boots all summer would be difficult.
