Paper patching jacketed bullets

Well the problem that you have is the paper gripping the copper. IF it doesn't then it cannot help impart spin. Which is why it isn't done today, I'd wager.

I'm not a paper patching expert, not even very experienced in it at all.
I have done a little though, I'll add my .02 - worth what you paid for it.

The direction of wrap matter, some say wrap in the direction that will cause the bullet to unwrap the patch and shed it as it leaves the muzzle. The other guys say the rifling will cut the patch and wrap in the opposite direction which will cause the patch to tighten as it travels down the bore. Guys loading for microgroove barrels prefer the wrap that tightens.

One wrap won't work, it needs to stick to itself so 2 wraps is best. Some do more.
I live and size after the patch has dried, just so I'm sure of the diameter .

What your wanting to do should work, I'm going to guess the accuracy will be poor. The jacket is hard , the concept depends on a soft lead bullet that can deform some and conform to the barrel. Your jacketed bullet won't do that, I'd predict the patch will be damaged trying to muzzle load it too.

I could be wrong about all that but in my opinion , it'll work but with poor results.

What diameter you wanting to get to?

Some folks have paper patched jacketed BPCR bullets and for smokeless cartridge loads too.
They mentioned a couple of articles written about it, one pertained to patching a .30 caliber bullet.
It said to roll the bullets with a file to raise bumps on the jacket.
Someone posted a photo of a fired PP jacketed bullet and the engraving from the lands were smooth but the rest of the shank was slightly rough.
Perhaps the roughed surface helps the patching adhere when fired.

That's not about muzzle loading, however where there's a will there's a way.
Precision ML shooters often use jacketed bullets that have been precisely sized to their bore using an expensive sizer such as the Swing-Lock bullet resizing die.
That has made paper patching unnecessary.
However if someone still wanted to try paper patching, then perhaps with a properly sized bullet and the right paper patching technique, someone could probably do it.

Here's a thread about the Swing-Lock resizing die which can actually engrave the bullet with rifling grooves that match your barrel. --->>> https://www.thehighroad.org/index.p...le-bullet-resizing-dies.872769/#post-11592692
They also make the same resizer without the rifling grooves, and there's a short video of it in action.

This thread is about the accuracy of precision long range muzzle loaders that use the Swing-Lock resizing die. --->>> https://www.thehighroad.org/index.php?threads/arrowhead-custom-muzzleloader-starting-4k.872036/
The Arrowhead Custom ML outfit made the video showing the Swing-Lock resizing die in use.

Ross Seyfried has written a number of articles regarding paper patching jacketed bullets to fit odd sized bores that bullets are either unavailable or prohibitively expensive. Works just fine.

9# onion skin is .002" , 2 wraps will add about .006". Sounds weird but there will be some stretching & shrinking. So you'd be right there with a double wrap. Like I mentioned before, I don't know if the patch will survive being muzzle loaded. If it were me, I'd do a double wrap, coat with lube of choice and size it to .505. That'll iron on the patch some and help prevent the patch getting cut too soon. Interested, I'll be watching if you do try

Sounds like you would have to wipe the barrel well between shots, as loading down a fouled barrel might be pretty hard on the paper. ?

Is that the bore diameter? Most tc .50’s seem to come in right at .50/508”. You could probably shoot that bullet as it is.

I’m shooting mostly paper patched bullets these days. Sized under bore size, paper patched and then sized to bore size. A clean barrel is a must.

Can we see your bullets?
Using soft lead?

Here are a few. 300 grain grease grooved and 330 grain paper patched.



and yes. Soft lead for hunting, up to 20 to 1 lead/tin alloy for targets. The GG bullet is sized .401” and a nice fit for the .400” bore. The paper patched bullet is sized .396” patched and then sized to .400”.
