I agree with a light crimp and saving the work on the brass. If you ever want to try different bullets, consider moly coated. I get less smoke and very little fouling with 4.2 grains of W-231 and 158 grain rnfp from Bear Creek Supply bullets in 38 special. I haven't tried them in .357 but would expect the same performance at medium velocities. I shot quite a few Missouri bullet company lead and was pleased, but indoors I would get a lot of lube smoke and a headache from poor ventilation. I haven't had those problems with moly at all. I keep the plain lead for outdoors only now.
