I have a small supply of Longshot & would like to try it in .357 Mag. with cast boolits. My Lyman books that have CB loads are dated & do not list Longshot. My 2018 Hodgdon book only shows Longshot with jacketed bullets.
My molds for the .38spec,/.357 tend to be on the heavy side. Here's what I have to choose from:
Lyman & MP version of #358429 (both versions weigh .172-173gr, with my alloy)
MP-359 Hammer (solids weigh 173, PB wide HP weigh 158 & penta HP w/GC weighs 166.5 sized, lubed & checked)
Lyman #358423 weighs 160
SAECO #382 (supposed to weigh 158,but weighs 165 with my alloy)
RCBS 38-162-WC (GC) weighs 169 sized, lubed & checked
Arsenal 360-162-RF weighs 162 with my alloy.
Lee 150RN (weighs 150)
The Hodgdon book shows the following for jacketed.
158gr, Hornady XTP: 7.3 gr, for 1258fps start load & 8.4gr. for 1394fps max.
170 gr. Sierra JHC: 6.8 start load @ 1182 and 7.9 max. @ 1322fps
I'm thinking trying 6.8 with the RCBS 38-162-WC & the MP-359 Hammer penta HP w/GC
Any input will be appreciated. They'll be fired in a Ruger BH.
