and what i fail to see is that you old timers do not time into account RIFLING DEPTH from one gun to the next.
I'd love for one of you that can shoot all day long without loading getting hard, to put together a video, showing this, along with a 100 yard target, shot off the bench of course.
First of all, I apologize for -re-posting this video to those who are tired of seeing it.
50- maybe 60 shots that day by me on the trail, and Hatchet Jack - probably 80 or more. He starts at sun-up - we start at 10AM. No wiping at any time - either of us.
I'm shooting a .445" ball and 10 ounce denim patch- about .0225" compressed in the calipers as hard as I can squeeze between forefinger and thumb on the jaws.
This is Taylor shooting his Virginia rifle, .50 Rice barrel with a .495" ball and .020" patch. If mine, I'd be using a thicker patch as they will hold slightly if the powder charge is increased much over 85gr. 2F. For me, it's too thin- but it bloody well works well for him- no wiping for an entire day's shooting.
Here's a shallow grooved SXS rifle in .58- a Kodiak. I am using a .562" ball and .0215" ticking patch. The rifling is shallow- but is a cut rifled barrel- .008" on the rifling, so with the patch and ball, there is .0045" compression in the bottom of both grooves. I've shot 30 or 40 shots in testing for regulation that day when I decided to make the video. I am using the rifle's 3/8" Hickory rod- a replacement as the rod I got with the rifle was maple- garbage as a rod.
