Okay, I finally got a few quiet moments to myself last night and wandered out to the garage to try out the Herters sage dies in 357 and 429 last night. I took some reject casts to sacrifice up and was not too impressed.
Then I recalled the leftover commercial cast 45 Colt boolits I have gathering dust in the corner of the storage rack. They are a .454 300 gr FP, so I ran one up the 429 die. I shaved off a thick ring of lead and lube and ended up with a .430 dia 290 gr SWC! I was really surprised to see how much longer the boolit stretched out. It even has a faint remnant of lube embedded around the boolit.
Then I remembered some cast 32 cal SWCs (about 95 grs) so I ran one of those up the 357. I got a squat SWC that didn't amount to much. So I dropped another boolit into a 357 1/2 jacket and ran that up. I ended up with a 115 gr 1/2 jacketed SWC. It just might end up in a 9mm Luger case or maybe a 9x23 Largo for the Astra 400 (when I get a new firing pin, that is).
The biggest success came when I discovered my cache of Hornady roundballs in .490 and .530 diameters. THIS IS THE WAY TO FLY! I made a 170 gr 1/2 jacketed SWC for the 44, then a 205 gr 1/2 jacket SWC just by running roundballs of each diameter up the die and then adding the 1/2 jacket on the second pass. I was left with a thick lead "washer" around the seater stem, especially on the .530 ball.
I took a pair of lineman pliers and squeezed the sides of a .530 ball to pre - reduce the diameter and then ran it up the die. This left me more lead to increase the size of the boolit and when combined with a 1/2 jacket, gave me a 260gr SWC for the 44.
I now need to find some .375 roundball CHEAP to get a better fit for the 357. I can get a 125gr 1/2 jacketed SWC with the .490 ball, but the lead rings are taking away more weight than I would like.
Anyone have a better idea to "PRE - REDUCE" the diameter for a better fit? I think I will try my Lee sizer dies to see what happens. I just want to find a way to do more at a faster production rate.
