Great! loading... that is what I was hoping for - I think you have answered the question I needed.
What we are finding or I have found the 45 caliber rifles are a lot closer to have a common bore diameter than do the 50's. We might be able to amke one bullet that will serve 80-90% of the 45 bores on the market.
I will get some pictures of my breech area the next time I shoot for comparison.
