Whenever the gubmint regulates things, it's pure grief for the consumer. Specialized slug guns, barrels, scope setups and/or loads arose out of regulations against rifles for deer gun seasons. Hunters moaned about steel shot when it was forced upon the duck shooting community. Consumers are forced to spend more money and learn new tricks being the old dogs they are. The same things happened to automobiles. The wonderful EPA was born in 1971 under the watch of Nixon and cars got spendier and more painful to buy, upkeep and drive.
