Lee makes a mold for a 405-grain hollow-base round-nose bullet. It’s got wide, deep lube grooves. It’s a bit picky about casting; you have to have the temperature right, and the amount of drop from the melter to the mold right. But when you get it right, it makes a quite nice bullet. I haven’t tried it much with black powder(those I have gave so-so results), but with Accurate 5744 it works very well. As in consistent groups like this at 100 yards
And, compared to, say, a full-power load with a 500-grain bullet, recoil isn’t bad. I really want to try this one at longer range next time I get a chance.
On the 500-grain, I’ve been using those with a wad between powder and bullet whether using black or 5744 or Blackhorn 209, but I wanted to see how it’d do without the wad. Not bad at all
One other load tried is the Lyman 330-grain* hollowpoint. That's one I haven't tried with black at all, just A5744. Prior to this I used a wad under the bullet and paper-patched(patched because "Why not?"), figuring the wad would protect the bullet base. This time tried it sized .459, no patch, and no wad
The other try was the Lee 405-grain round-nose flat-point bullet, much like the original. These were cast of mongrel alloy over the base load of 26.0 of A5744
*It comes out right at 340 from my mold
