Have any of you had experience with these bullets in the 357 Sig? They are a 124 Grain JHP. The problem that I am having with them is this, the base of the bullet is larger than the rest of the bellet. When I push them in the case to the proper depth they are loose and want to drop into the case. If I put enough crimp on them to haold it forces the shoulder back and bulges the case. Have any of you had this experience and what did you do about it?
