Those are beautiful bullets you make. That 1-18 twist must be a great long range shooter when you get the rifle bullet. And talk about some thump at the end of the rainbow... must be really something to shoot.
I use a LEE mold and cast a 405 grain that is really a 423 grain of pure lead, in .457/8 diameter. Then I size them down to .451 diameter. I shoot them in my White M97 Whitetail Hunter. That rifle has a 1-20 twist I believe and it shoots them really accurate. No paper required. I was shooting them out of my 1-20 GMB it might be a 1-28 twist. They were hard to load, but they were accurate with 70 grains of Triple Seven 3f.
How heavy of a bullet would you recommend out of the .45 caliber to shoot?
