38spl and 357 loads for the Oregon Trail 180gr?

[oregon45]

So I was doing some cleaning the other day and ran across 1500 Oregon Trail Laser Cast 180gr .357 bullets I'd laid away back when I had a .357 lever gun. Don't have the lever gun anymore, but do have a profusion of .357 revolvers.

What loads should I try in either 38spl brass (for S&W 27's and 38/44's given the shorter cylinder) or .357 brass (S&W M586, Ruger GP100, Blackhawk, etc.)?
