I'm using a max load of Lil'Gun in my .357 Winchester '94 Trapper.
170gr Speer @ 1825 fps
BGunn: is that the 17gr load listed by Hodgdon? I think I'm heading down that road too.
I've got an IMI Timberwolf and a Ruger 77/357 that I want to try this in.
I've seen one person who claims to have gone as far as 19gr under a 170. I'm a bit skeptical of those claims though.
FYI, that Speer 170 GDSP is now called Deep Curl although the part number hasn't changed (4230).
