New bullets
I just got done with making 160 of my 409 gr RCBS 11mm .446 rifle bullets. They were weighed +- .5 grains. and the hardness is 8.5 BHN. On my hardness tester my old bullets were .045 these test at .050 the hardness is as close as I could get it. I dropped in one 400 gr piece of hard lead and it went from .042 to .050 and that was in a 10 pound melt. These are going to be awesome. Ron

I'm still having a hard time believing this is a muzzle loading bullet instead of a cartridge bullet. How does the bullet expand to form a seal going down the barrel? Does the paper work to form the seal? How soft is your lead?

rafsob, this bullet is a 11mm rifle bullet, It was made for a BPCR. This bullet is being launched at about the same speed as it was intended in the BPCR. I also use a Lee 500 S&W bullet for a paper patched ML bullet.
I use a over powder wad and the paper patch helps to snug up the fit. The over powder wad is the main seal and the paper is there to protect the barrel from the lead and the lead from the barrel. Think of the paper as a sabot. I have customized the lead to what works the best. This rifle like the lead to be 8 to 8.5 BHN. Ron
