paper thickness

[white eagle]

what is the most you can cover with a paper sabot
could you make one to cover .042
say to go from a 45 cal rifle boolit to a 50 cal m/l?

With a .002” thick paper, you would need 10.5 wraps I think.
That’s quite a bit of an increase needed.
If you are thinking of paper patching a .50cal muzzle loader, I have a mold that patches right to .498” that may do the trick. I’ve used it in a 50-110 rifle and it works well but requires a lot of neck sizing in that particular rifle.
Will need a pretty fast twist for it to work in a ML I would think but I can send a few your way to try if you want.

To wrap from 45 cal to 50 cal would require .045 total. That's 2 wraps of .01125 paper. Going to be stiff wrapping paper that thick. getting it to lay flat and form tight will be harder and getting tight folds on side to base corner with base laying flat is going to be hard. Even wet / damp getting it to wrap tight and stay tight will be a trick. Your probably going to need a poster biard type paper to get close to that thickness. The other issue will be if it releases consistently from the bullet.
.002 thick paper in 2 wraps, wraps easily and releases at the muzzle. If you need .498 then a bullet .489 - .490 should do the trick.

correct.

You can do it with a cross patch with a selection of craft paper loaded in the cartridge case. I did it using my .50-90.

How was the accuracy?

Missed a few on a 8x12 swinger at 180 yards and never did it again.
It was just a curiosity thing.
