I just have a disdain for legislated concepts.

The 38 Super is adequate for deer, but the 9mm and 38 Special arent.
The 350 Legend is only a great idea because certain legislators created its existence, but the 351 Winchester Self Loader of over a hundred years ago is supposedly anemic turd and NOT legal.

3 inch slugs, sabot slugs and rifled slug barrels all came about because of legislation and ways to circumvent it. Muzzleloaders too. All useless and not in the interest of cleanly killing anything.
