I finally finished up my project molds I found 3 old dual cavity Lyman wadcutter molds on Fleabay. The first two had some rusting and needed cleaning, the Ideal 358-432c was in like new condition(still required a good cleaning.
Left to Right, all cast same isotope alloy 11bhn
Lyman 358-495 drops .359 @148 grs
Lyman 358-432s drops .361 @ 153 grs
Ideal 358-432c drops .360 @ 162 grs
normal 158gr SWC for comparison..
The 148gr and 153gr when seating to crimp grove, will protrude into the case .370, The 162gr has a noticeably larger bottom driving band so it protrudes .390 into the case. The standard 158grSWC for comparison protrudes .330 into the case.
Loading in .38 special brass, with standard velocity loads, the 148, 153 and reg 158swc can use the same loads. I did have to work up separate loadings for the 162gr since is has the longest shank. I'm liking 3.5 grs of HP38/231 for 770fps across my Labradar, or I can go 3.5grs of Green Dot for 815fps.
