If the regulators knew enough about firearms, which they don't, they would have used the term non-bottlenecked cartridge instead of straight wall. In Louisiana, which allows single shot rifles, 35 caliber or larger, for primitive season, the Ruger #1 is excluded because it does not have a visible hammer. They meant for the law to say manual cocking hammer, but screwed it up. As we all know, I can see my #1's hammer by looking thru the hole in the bottom of the action. Louisiana has not ventured off into the straight wall/ bottleneck cartridge debacle yet. I think for all intents and purposes, we can call the 327, 357, 41 mag, and the 44 mag( and others) straight wall. Bob! :wink:
