I have been unable to find a round-nose, 200-grain mold for my 44-40 Vaquero. I did snatch up a Lee tumble lube, 230 grain, .430 swc. I cannot find a load for this for 44-40, so I was wondering if I could use this bullet and seat it to the same depth as the 200-grain bullet. This would put me at the third ring from the top of the tumble lube rings. Does anyone see a problem with this? I'm also going to go down to 5.25 grains of Trail Boss instead of my normal 6.0 grains. Just to let you know, my cylinder has been bored out to .430 and the barrel is .429. The chambers were .425-.426. This was a common problem with the early Vaqueros. My test loads for the Lee .430 do fit the chambers.
