tinkerfive Posted July 2, 2010 Report Share Posted July 2, 2010 Hey all, I just got a Mauser with a sporter 30-06 barrel. The rifeling looks in perfect condition. The shape of the lands is something that I've never seen before. Rather than flat across the top of the land there seems to be a dip giving the land an over all "U" shape, or kind of like looking down RR tracks. The proof stamp sort of looks like a pair of scissors with one of the loops missing. I'm thinking that it should be a combination of the possible letters K,X,P. Anyone have a clue about this?

gun nutty Posted July 3, 2010 Report Share Posted July 3, 2010 How many lands/grooves? 4? You can talk about the benefits and disadvantages of different rifling systems on barrels. Proof's in the pudding... How does it shoot? Quote Link to comment Share on other sites More sharing options...
machinist1 Posted July 3, 2010 Report Share Posted July 3, 2010 Tinkerfive. What you are describing sounds like Paradox Rifleing to me. There are on sharp corners for fouling to build up in. I have a Kahr K9 that has this rifeling. Bob Quote Link to comment Share on other sites More sharing options...
tinkerfive Posted July 4, 2010 Author Report Share Posted July 4, 2010 How many lands/grooves? 4? Proof's in the pudding... How does it shoot? It has 6 lands and grooves, just got it so I haven't shot it yet. I'll bet it's just a more modern rifeling process than I'm used to seeing. Now if it were Polygonal, I think that I would have recognized that. Quote Link to comment Share on other sites More sharing options...
roscoedoh Posted July 5, 2010 Report Share Posted July 5, 2010 Could it be Enfield rifling perhaps? Quote Link to comment Share on other sites More sharing options...
Vladymere Posted July 6, 2010 Report Share Posted July 6, 2010 I know in Germany, and maybe other countries, that in the early 1900s with the advant of jacketed rifle bullets the lands of rifleing where rounded so as to not cut the thin jackets in use at the time. Sharp edges on the lands where able to cut the thin jackets makeing the jacket peel apart. Vlad Quote Link to comment Share on other sites More sharing options...
