In the not too distant future will we be able to buy a rimmed rifle cartridge that isn't a 30-30 or 45-70? If smaller ammo makers start to make them, will we have to pay a buck apiece or more? It seems every few times I go to the range I find cartridge cases I have never heard of. Is there really a need for all these new cartridges or will they quickly fade away like so many that have been brought out in the last twenty years. I wish the big ammo makers would just make brass for the guns we own now instead of some new 6.32 whatever for the AR platform. A friend of mine has one of those rifles and he said he is able to shoot fourteen cartridges in it. He changes barrels and whatever to accomplish this. That would be a big brass headache. Not my world.
