[QUOTE="J E Custom, post: 1812311, member: 2736"] This below from their website, have you found this to be the case? I've not heard anybody ever mention micro rifling, and certainly not its ability to prevent copper fouling...all very interesting but curious what your personal experience has shown. "The bore after lapping is micro rifled. Micro rifling are the very fine longitudinal grooves left in the surface after lapping. This micro rifling, together with the slight choke in the muzzle helps prevent copper fouling. The maker says you probably don’t have to do a thorough clean until 300 rounds."[/QUOTE] I became interested in Ballard rifling (Micro grove/rifling) many years ago and found it to be very good from an accuracy standpoint but I saw little difference in fouling characteristics In higher velocity cartridges, There did appear to be some improvement with big bore cartridges, but that could just be a results of the slower velocities. Micro grove/rifling came along before we understood the benefits of lapping and a proper break in so real world experience is limited. Here is a paper on Micro grove that explains the purpose and use and will give some a better understanding of this type of rifling. It's interesting though that the big navel guns have this type of rifling, so someone though out of the box/norm and decided that In this application it should be better.

It could be that break through that changed the gun/shooting world. At least we get to think and debate about it. J E CUSTOM [/QUOTE]
