I am building a survival gun based on an overunder shotgun (a poor mans Kreighoff). I plan to cut the barrel down to 22" and have a custom barrel insert made for the upper chamber. I plan to leave it in permanently, but it won't be fixed should I ever decide, or need the double barrel 12ga. I live in South Florida, but sail down to the Caribbean, travel throughout the Eastern US, and up into South Eastern Canada and plan to keep this in the boat/car during any of my travels. My inclination was first .30-06 or the .308win as for the obvious all around advantages each offer, but a friend suggested .357mag. The .357mag buffalo bore from an 18" barrel produces something like 1800fps which is impressive. The .357 ammo is smaller which will allow me to carry more on the buttstock. The other advantage would be the ability to shoot .38spl wadcutters at small game offering dual purpose. Also being that the bottom chamber will still be a 12ga, I will have the ability to both shoot shot for fowl and sabots for larger game should I need to. I plan to attach a sling to the shotgun to carry 24 shells, and have a pack on the side of the buttstock to carry a handful of rifle cartridges. The obvious advantage of the .357/.38 is that I should be able to carry twice as much ammo over a traditional rifle cartridge. I considered carrying several other inserts but it didn't make any sense given the lack of storage.
The other other advantage being able to carry a .357 mag revolver as backup and share ammo. But this is of lesser importance.
I would like any of your ides on this and is it a feasable choice or should I just go for the .308 and carry less ammo and lose the ability to hunt varmits?
Your experience is appreciated on this. Thanks
