IIRC, the original 11mm Mauser round was PP. Recall that from some research that I did yrs. ago when I purchased my Amsburg M1871.
I started PP for my .45 Sharps rifles last year. As Don said, it is time consuming.
Swaging Pb to form the bullets produces very good and void free bullets, but the dies and press are very expensive. Store-bought swaged bullets are available, but the buyer is paying for someone’s labour and tooling as well as shipping.
A good how-to-do-it work is “Loading and Shooting Paper Patched Bullets “ and available from Buffalo Arms:

My biggest bugaboo is rolling the patches, but then I made a patch board and that greatly increased the quality of the PP.
I also found that the more I roll, my hands work better and faster. PP’ing definitely requires a knack that only comes from repetition.
I shoot a flat based non tapered bullet, about 500 grain from 20:1 alloy, with a “Gov’t style” nose and is .434” dia. I patch with yellow legal pad paper and it brings the patched bullet up to approx. 446-448.” dia. The patched bullet will obturate to fit the bore upon firing. GOEX Fg and standard WLR primer, w/ a grease cookie to keep the fouling soft.
I found that when shooting the old/obsolete rifle calibres, it is best to duplicate the original loading -- inc. the bullet -- as far as possible for best results. You are one step ahead of the curve and have an original round to break down and measure.
If you do break down an original round, would you post what you find?
Steve Brooks is a very good mould maker. He cut my PP mould and moulds for several other shooters. When ordering a mould give him a call and see what information he has.

Since, your rifle has a damaged crown, all bets are off as to its performance with PP.
The most important aspect of this signature line is that you don't realize it doesn't say anything significant until you are just about done reading it & then it is too late to stop reading it....
