Not what you asked exactly, but might be of interest
I have used the 150 grain SWC ( Lyman 358477) with both Trailboss & Titegroup in my 1946 S&W post war S prefix. ( aka pre Mod. 10 )
I didn't cast my own though.
A good friend (now passed) would cast these and I still have a good supply.
I use the same load in my Commando
