I'm looking for load data for .357 Mag. with 170 Grain Speer or Sierra. I have the latest Speer manual, but it doesn't have any data for the 170 Grain bullet. Don't know where my Sierra manual is.
Any help is greatly appreciated.

R WEST....My Sierra manual is ready but you'll need to mention which powder you want to use.

jagtip -
I'll be using W-W 296 and/or H110.
Thanx,
