Pope style rifling or conventional?

Roger
Thank you for offering those barrels. I'll pass on them though. The whole point of this exercise from my prospective is to acquire a barrel with Pope type rifling. I want to do some very specific shooting tests with such a barrel.
I already have an RKS barrel on my BR rifle and that sucker really shoots. So I'm not in need of another barrel with conventional type rifling.
I appreciate you taking the time to give me the specs on those barrels.

I wonder if you were to greatly magnify the bore of a single-cutter cut-rifled barrel if the bottoms of the grooves would also look fairly flat like the pope-rifling. The top of the cutter might be more flat, than radiused, like you might think.

I own two RKS barrels. Both in 40-cal. Both are right-hand, gain-twist barrels and both are S.S. I shoot GG bullets, in Silhouette competition, and do not have any issues with leading. Both barrels are very accurate. RKS also has a method that produces choke in his barrels. Ron recommends S.S. barrels for lead-bullet shooting as the finish in the barrels is smoother than his carbon-steel barrels. I believe he laps his Carbon barrels but not his gain-twist (I've heard elsewhere to gain-twist cannot be lapped due to the changing angle of the rifling).

Ron of RKS also uses a single-cutter rifling cutter as did  Pope.

Ron does not do anything to choke his barrels. He told me that the taper in his bores are like all single point cut rifled bores. There is a taper in the bore due to wear of the cutter. He does not lap his barrels. 

Gain twist barrels can be and have been lapped with segmental laps. Leather laps and other gadgets.

The square bit reamer with a wood backing used by many barrel makers also leaves a taper in the bore for the same reason.

Barry Darr barrels were choked and button rifled so there was no cutter wear. Apologize if off original subject and just wanted to share it was and has been done.
