I shot .357 maxi in a Super 14 contender for a while in the late 80s and again in an 18" custom shop contender carbine barrel around 2000 or 2005. Cool cartridge.

If you're not finding data you must not be trying very hard. There is a lot of data out there. Speer, Hornady .. etc. Try the Speer 180 grain flat point, Hornady 180 grain SSP, Nosler 180 grain Partition, and Hornady 180 grain XTP .. some of these are discontinued. As suggested, H110 or 296 for bullets 160 grains and under, AA1680 for 180s and up.

As a f**k around load smile try an 88 or 90 grain 9mm JHP with a case full of H110, sorta roll crimped over the bullet shoulder. Not extremely accurate but man will they tear up a ground squirrel if you get close enough.

Anyone who thinks there's two sides to everything hasn't met a M�bius strip.

Here be dragons ...
