Is that one the hollow point SWC? If so, mix your lead rather soft and it will work like magic. Anywhere from 16:1 - 20:1 depending on the velocity you push it.
No Kevin, just a run of the mill two cavity Lyman Ideal.
I used it for the first time today and ended up with about 200 keepers.
Mix was mostly WW with some other misc. lead pieces.
Sized to .358, lubed and loaded in .357 cases over 4.5 HP-38.
The casting seemed a little easier than 358429's and 495's.
