Ditto here, I have a box or maybe two from Montana bullets, 135 grain gas checks and no load data, I remember finding it somewhere, but can't find the source now. Should have book marked that page.

Never shot cast 150 with nitro, did shoot jacketed.  I'll see if I can still find that load...

Joe,

I haven't tried it, but there is a single lone 32-20 load listed at 27,000 cup using a Lyman 150gr #311440 flat nose that is shown at the following link...

In the next link, Shuttleworth mentions two loads using .321" dia bullets, but one is for a 125gr bullet weight, and the other might be too...

This is my chrono results for Elaines 32/20, with a .308 barrel. The pressure will be less than a .317 barrel and the velocity will be a little less.

The 180 gr bullet loads will also have less pressure but, it will have more velocity.

It might give you a starting point, if not, it should give others that have a .308 barreled 32/20, some valuable info.

All loads use original Smilley lube (similar to JSL), BSed in a 26" bbl.

10.2 gr, 296, 1407 fps F205M, ave 20 shot string, good load

Switched to 9.5 gr #9, Didn't Chrono but, it shoots a little better. It should have about the same velocity as the 10.2 gr load of 296.
