The NRA Cast Bullet Handbook has a number of articles about paper patching in cal. 30-06, and Lyman made at least 2 molds for paper patched .30 cal bullets. Unfortunately, the Handbook has been out of print for a whole bunch of years, and I just checked Lyman's 4th Edition Cast Bullet Handbook and it looks like paper patch .30 cal. molds are no longer listed.
I'm not computer savvy enough to be able to send you stuff scanned from my copy of the NRA publication, but maybe some of the other Forum members could help. Although I've never tried paper patching, it looks to me like the articles in the Handbook would be a real good place to start.
Just did a little more research: Lyman mold numbers are/were 301618 (160 gr.) and 301620 (196 gr.) In the '06, they suggest 53 gr. WW760 with the lighter bullet and 49 gr. WW760 for the 196 gr. bullet. CCI 250 magnum primer for both loads.

Mark 1960; You could get a copy of "The Paper Jacket" by Paul Mathews, it is available in a number of places. You can also find a ton of info on the "Cast Boolets" website in the "Smokeless Powder Paper Patching" threads. Those guys have done a ton of work on this subject.
Any mold or bullet from 150gr to 200gr.+ can be patched for the 03A3. I would get a push through type sizing die .001 to .0015 " larger than the bore diameter of your barrel, and wrap the bullet from the ogive back with wet green bar computer paper , two wraps so that it is .002" to .003" over groove diameter. There is a technique for using a cigarette roller which I am told makes it a whole lot easier when wrapping bullets under 35 cal. Let dry and lube the bullets with JPW, liquid allox or whatever and load. Preferred powders are slow enough to fill the case. Use jacketed bullet load data.
Thais is a very brief synopsis of what I have been told works. You can use many other papers than green bar. Just remember that the thickness will be multiplied by four when using two wraps. Don't overlap the ends of the wrap. A slight gap is acceptable.
You can also size the wrapped and dried bullet with a push through sizer just lube with paste wax, LLA or some other light lube. If you size down to .309 the bullet jacket will typically swell back a thou or two after a couple of days.
I'm going to test fire some PP loads in my Argentine '91, hopefully tomorrow. Lee 150 and Ideal 308413(squib bullet). I decided to work with two notoriously difficult bullets. The only thing I know for sure is the JPW I put on the paper has turned the paper jacket into an amazingly tough item. Both are finish sized to .315 and really fit my gun. Jacketed bullet charges of WWII 4831 and Winchester magnum primers. We'll see. Oh, I don't have to size the already fireformed brass, I know that for sure too.
