I shoot about 50%-50% PP and GG bullets, The PP are a little more work but a lot more fun. I dont even use dies (except for a Universal Decapping tool), I use fire formed cases my bullets are of a diameter that is a couple of thou. under the ID of my cases with the paper rolled on them. I wet the paper before I roll it and then after it dries it pretty much stays in place. I then smear a very small amount of lube (SPG or your choice) on the patched bullet.
I seat my bullet as I shoot. I load the case with powder (Black of course), compress and cap it with a card wad. When I shoot I place the patched bullet about 3 - 4 mm into the case mouth, insert the round in the chamber and the seating depth is then set by the (uebergangs kronus). I am unsure of the word in English, (Lands maybe).
This method works great out to 200 meters (the longest range that I can Shoot in Austria) in my 45-110 Shilo, and my 45-90 Pedersoli.
To determine the correct size bullet for your rifle you can make a cast of the chamber thentake the OD and subtract the thickness of your case wall, then find a bullet size that is a couple of thou. smaller( with the paper wrap) than the ID of the case. That method is very complicated, I just measured the ID of my fire formed cases and sized the bullet to that. Quick and dirty, but it worked for me.
