I hope I'm not covering old ground here. Couldn't find it elsewhere. I have a 20" CMP chrome bore barrel and I can't figure out what the turn ratio is. I tried a marked cleaning rod and patch to see how much it turned, but it didn't turn. Do all of these type barrels come with the same ratio or do they vary? There's no manufacturers name or mark on it that I can see. I would appreciate any and all help. Thanks.
