If you are talking standard bullets 110, 125, 158 then just crimp into the crimp groove and you'll be fine. I don't recall having any problems with 180s either that I used to load (but that was in a NM) .
According to gunblast the OM .357 Cylinder length is 1.602 . The head on a cartridge is .060 ... So absolute max is 1.662 which is really tight. From Spec. 1.590 is max OAL.
