Do paper patches come off like a sabot when fired?
Do paper patches come off like a sabot when fired?
They should turn into confetti when the bullet leaves the barrel.

I like that short video RFD. Shows a lot more easier than it can be explained in words.
On a dead calm day I recover the under wrap of the patch about 3-5' in front o the barrel The confetti from the outer wrap is in the same area, Examination of the recovered patches can tell you a lot about how the load is doing. On most of my loads the inner wrap isnt cut but does show engraving impressions on it. The fold under is clean . I wrap tail less. Ideally you want the patch to release as close to the muzzle as possible.
Does it matter which way the paper is rolled on?

my chase one wrap from 18 pound paper comes off in one piece. their are slashes in it from the lands but it stays in one piece. it comes of the instant the bullet leaves the muzzle.
And sometimes you recover boolits and they have some paper on them. The less violent the action the paper is subjected to the more likely some may cling.
With .69 caliber (three grooves of width equal to the lands) I found the patch material in front of the bench to give good indications of how the paper was performing. That it would fail right at the base of the boolits kinda surprised me and gave me a clue as how to remedy the situation.
Oh, speaking of remedies, if anyone knows of a lubrication mix that will help paper resist the fiction of the bore please do speak up.
I'll go post in the muzzle loading section.
Nothing seems to work quite well. If you have issues with the paper, it more likely is due to gas cutting, not to friction of the paper in the bore.
The scorching of the paper isn't due to friction, but rather to gas cutting, so one should take measures to avoid it. Putting something on the pp is just dealing with consequences, not the cause. A better overpowder wad is a much better solution.
The video is quite interesting in that the bullet exits the bore "clean" without the puff smoke seen with almost all videos showing the firing of a bullet. I guess when you put a bore fitting "cork" in the barrel there is no leakage past the bullet.Could only contribute to accuracy and velocity, I'd guess.
Late to the party, but I've shot a few PP boolits and watched more shot, the confetti is like a small parade. Cute.
I use JoJoba oil to lube the patch after its wrapped on, A small drop on thumb index finger and middle, wipe 5 then use a cleaning patch to remove any excess. You dont want the wet look just a shine or gleam.
I noticed that the bullet in the video yawed a little and then settled down after the paper patch came off. Is this normal and does it effect accuracy? This is the firswt time I have ever seen a video of a paper patch bullet. james
I'm not so sure that what appears to be yaw, isn't more of an affect of camera angle.
Accuracy with patched bullets, assuming good bullet fit to the chamber and bore, and a paper that will shred on it's trip thru the rifling, and of course accuracy of the powder charge, fouling control etc., paper patch will shoot just as accurately as any other type of bullet, if not better.
Long range rules, the rest drool.
Good Cheer ... I used Rooster Jacket lube on my paper, a light swipe with the finger seems to provide results
