HHI 812:
Although the dies I have make .411 bullets, Mr. Corbin suggested that they would be fine for cartridges such as the .41 Remington Mag. I don't know if it's worth slugging the barrel just to make sure if the .411 is okay. I've been told that, in general, .001 over might be better for accuracy. (??)
I have a .411 JDJ, which is a .444 Marlin necked down to a .41. As you have found out, there's not too much available for the .41 - that's why I invested in the swaging dies. I haven't had a chance to swage up any bullets for it, though. I was told, too, to use bullets designed for the .41 Remington Mag, but with a higher velocity from that a .411 JDJ (or your .41 TSM), I think a semi-spitzer/spitzer/spire point bullet with a heavy jacket would be better. People complain that the the higher velocity .45-70's will lose their jackets, so I'd guess a faster moving .41 would be even worse....any comments, Donna? But, for plinking, I'm sure the .41 Remington Mag bullets would be fine.
The dies I have will make a 3-S (semi-spitzer) and also a 1/2-E (round-nose). I also have the copper tubing jacket maker kit. If I find the room to re-mount my press, I'll try to swage some up this weekend. I'll let you know how they turn out!
