THIS feature ought to be added to my previous plea for cryo-quenching - ESPECIALLY in revolvers and rifles. It’s been shown to improve accuracy because of the more “squeeze” it puts on jacketed bullets, and it increases velocity, while it decreases barrel-wear. When combined with “cryo”, we ought to have some really high-quality, kick-ass smoke-wagons. If you’re shopping, ask the maker if he offers THIS feature!

At the expense of being able to use hardcast, from what some sources say, though Tim Sundles from Buffalo Bore disagrees, at least with his brand….at least there’s choices..
Glock uses polygonal rifling in their 9mm barrels. I load hardcast when in the woods with a Glock/p80, but use aftermarket barrels.

Like everything, depends on use. In my days of shooting steel, lead and only lead that “evaporated” (maybe the wrong term) on impact was allowed. I know from shooting my G-44 that lead doesn’t work well. So, depending on how it’s used, I couldn’t agree more that different barrels should be offered for these various purposes.

Polygonal rifling is hard to compare on a bullet through a comparison microscope. That’s why when a Glock is involved in a shooting incident you prefer to use the discharged casings for your comparison. That is probably one of the biggest reasons they won’t make more guns with polygonal rifling.

Notice that I only mentioned JACKETED bullets in my post? Even HARD-cast lead tends to quickly foul this rifling pattern.

You mentioned them, and only them, but that doesn’t mean that’s all that’s out there.
