My new barrel has 5R rifling that I picked because it seems to have some real advantages over the norm. And no disadvantages that I can find.
What experiences have people had with 5R rifling?
What I don't understand is why only a small percentage of makers offer 5R and those that do only list a few barrels with it.
BCA, for example, lists 20+ 6.5 barrels but only a couple with 5R.
If it's so much better why hasn't it caught on more and started to replace conventional (ancient) rifling?
Edit: As a retired machinist I understand that it's not cut as easily as the older style, and that many people don't want to change from something that works "well enough". I wonder how many of we older guys just resist any change, period?
Companies that button rifle their barrels could make the change easily. Making new mandrels for hammer-forging wouldn't be hard either.
