Truckn14269, I've never heard of "Ridge and Groove" rifling. What's it shaped like? Or is that just another name for "Land and Groove" rifling?

603country, I'd ask what accuracy a rifle would produce with 30 shot groups with shots fired every 20 to 30 seconds apart so the issue of barrel heating changing point of impact. If the 'smith said it would start walking when the barrel got hot, I'd say thanks anyway then walk away.
