In my White rifles I fire off a cap or two to clear the channel. You can tell by the sound of the "crack" if its clear or not. Then I load the conical wrapped in white plumbers tape (one wrap) on top of the powder an wad. The plumbers tape simulates a fouled bore so I hunt on a clean bore. This has worked for years and again this past season. Not sure how it would work on a saboted load or a tight bore in other rifles, but sure works in a White!
