not as far as I know....the DE is designed to function at a certain pressure level, and will not work well unless you use the correct ammo type.If you try weaker springs , all you will do is batter your frame and slide more than normal, if it will even work. I have using only my own reloads in my .44 mag version. From what I have heard, the .357 is a bit pickier than the .44 because the pressure required to move that big slide is a bit tougher for the smaller round. I have been getting about a 99.8 % function level with my reloads. I have shot about 500 rounds thru mine in the 2 years I have owned it. Try Magtech ammo before you give up, since that is one of the few .44 ammo types recommended by factory, and I would expect it would do good in .357 also. . Otherwise . you would be better off if you reload for it....there is only one powder I use, Accurate #9....I have fired 250, 220 , and 180 grain bullets thru mine no problem.
