Plinking round = 158-gr LSWC, 4.5-gr Titegroup, .357 case, Federal 100 primer that chronos 900-fps from a 4" barrel. Nice and fun with low recoil and very accurate.
A lot more stout than my plinking round is a Lyman 358429 170-gr hard cast Keith bullet over a heavy charge of Unique or 2400 in a .38-Spl case. Those loads chrono around 1245 and is THE classic Elmer Keith load for hunting anywhere in North America. This is my absolute favorite combination of bullet type, bullet weight and velocity in the .357-Magnum.
An "in between" load is a 158-gr hard cast LSWC over 6.0-gr Unique in a .357 case that does over 1050-fps. With this load you know you aren't shooting a .38-Special.
The screaming-est .357 Magnum load I have on hand is factory loaded Remington Express R357M1 125-gr SJHP. From my 6" stainless Security Six it chronos 1660-fps ten feet from the muzzle!
