Lead is probably undersized. Was you .447 a typo? I have to use .459's or greater in my originals (to prevent blow by past the grooves. I've shot well over 10,000 rounds out of them over the years and once I found the right powder and right bullet size and such.. I've never had a problem. I do not re-size my casings once they are fire formed to my Springfield's. I do use a cardboard wad between the lead and powder.. the original carbines cartridges had a cardboard sleeve like a TP roll that took up interior space.
I had to do trial and error as when I started shooting, I was not hitting any targets and some old timers taught me about key holing and how to probably fix it.
Your lead sounds like it is on the hard side too... once it is formed to the lands and groves.. and with some lubrication... should go down the barrel with some good taps! I use an oak dowel that I made for a cleaning jag with a round ball on the end.
