CCI Blazer 158gr .357 JHP. A medium load suitable for practice and fine in your guns, given the 28 or so ozs you mentioned. I've carried this load on occasion after using it to 'break in' a new .357 at the range. Difficult to find, though, and the $ has SKYROCKETED, more so than many other .357 loads, from less than $20 per box of 50 to over $40 in some instances.
Another load is (are?) the 110gr .357 JHPs from the major mfgrs. We used these back in the 1980s when the Model 19/66 RB magnums proved nearly impossible to control with 158gr bullets. Some folks on this forum will say not to use them, that they will damage your medium or light steel frame magnum. No they won't: I've fired many of them in K-frames via quals, training etc. without a problem.
