I wonder how much Remington, and their new 360 buckhammer, designed specifically for straight walled cartridge states lobbied Tennessee to get this law passed. Whether it was directly, or indirectly, I can guarantee you that there someone representing Remington was there during any kind of hearing.
For real, if you wanted to go to straight wall hunting, just buy an existing cartridge, there's plenty of them already developed and time-tested.
45-70 gvt, .350 legend, 450 nitro express, and even 10mm (arguably) have been proven to be effective hunting cartridges. I don't know why we need more, other than companies trying to sell new products. I'd like to see the boxes of shelves full of ammunition for guns that already exist, rather than for ones that have just come out, and very few people own.
I think muzzleloader season should be an actual traditional weapon season. Flint and cap only, and maybe add week of CVA-type 209 primer guns for those of us that already own them.
I've taken more game with a cap lock SxS shotgun than anything else, and I've taken shots considered impressive even with a modern rifle.
I'm all for modern rifles, but I also like the idea of giving people who want to go out and experience hunting and its traditional form a chance to do so. There's just something different about taking game with lead that you have cast, from a gun that you built, and powder that you have milled.
