    MP 358-640 questions

    Looking at the MP 358-640 mold for my Colt Government MK IV .380 pistol. Does anyone have any experience with it? Thanks in advance.

    It is fairly blunt.
    Have you already tried a few to see if they will function in your particular pistol ?

    Nope, I have not. That was one of my concerns about it.

    I loaded one of those in a 9mm once and it seemed too big. I didn’t think I could get enough powder in it, and the HP got crushed by the seating stem.

    MP molds seem to be design for revolvers. Gigantic meplats in the calibers I shoot. I looked at their .40 cal molds tonight - not one will feed through my Sig P320.

    I bought his 165gr Truncated Cone 6 banger last month. They feed through my G23 with no problems at all

    Well, ended up buying a four cavity Lyman 356632 mold, with nutcracker handle. Works great in my Colt .380 MK IV Government.
