I have 12 Lee Mini's on the way and 15 paper patched 459-405-HB's that weigh 386 gr. I sized the patched bullets to .451 but remember if you think that they will work but you want them bigger you can paper patch them and size them to .454 or .452 and those are easy to get regular size dies that cost under 20 dollars.
Let me know how they work for you. I didn't have much luck with the naked Mini's. After I paper patched them I liked them. But the hollow base bullets shot so well I didn't go back. Remember to lube them before you shoot them.
I sent them priority mail so you should see them in a couple of days. Ron
