Was reading about Col. Harrison's early smokeless PP experiments in Mar. '72 American Rifleman. One of the things he tried with conventional two-diameter bullets was a PP that extended only slightly past the front driving band where it was folded over to anchor it there. The front bore-riding section was left bare like a regular cast bullet. Everything else was treated like a normal PP config. with patch lightly lubed and ogive contacting the rifling if possible.
He didn't discuss the results he got with this particular method, compared to full-length patching, and was wondering if any of you boolistas might have tried it? TIA ,
