    This is what my 200gr Berry's plated .45 bullets look like after I broke my first batch of completed rounds down.

    Completed cartridge on the left. New bullet in the middle and pulled bullet on the right.

    Is this normal? Too much crimp? Not enough mouth expansion?

    The plating does not appear to be cut.

    Is the powder charge light?
    Mid range?
    Heavy?

    If it's less than heavy, I'd proceed and adjust accordingly.
    If you started on the heavy charge end, I'd back of the crimp.

    I'm on the light side right now. These were pulled because they were too light to cycle the gun at all (4.2 gr HP-38). I've loaded a couple more with the same die settings but higher charges that have run better. The last batch I loaded at 5.0 gr cycled fine but were really sooty so I wanted to bump the charge a bit more.

    The latest batch I'm getting ready to load is still light, 5.4gr HP-38 but should run well. Before noticing this, I did expand the case mouth a bit more but have left the crimp the same.

    Crimp is fine then. It doesn't take much to hold the bullet under recoil. The plating is very thin. Some deforming is expected, as is with a lead cast bullet. Just watch for high pressure signs, but you're already seeing low pressure signs. As always with reloading, proceed with caution.
    Don't bell the case mouth more than necessary to just start the base of the bullet without shaving. Overworked brass fails sooner.

    OK, thank you, Vaq. I'm only doing small batches until I settle on a load I like for my M&P. If I can get just above the low pressure signs and still knock down the steel plates at my club, I'm happy. I tried to crimp just enough to get the rounds to reliably chamber. Sounds like I'm ok.

    It sounds like you're being observant and doing things on the cautious side of the scale. Thats exactly how it should be approached. Just my opinion.

    Looks like you are doing fine. And getting good advice to boot. Have fun.

    Find yourself some 200 gr semi wadcutters and you will never want to put any other bullet through your 45. My favorite by far is the Hornady combat target. They are Lazer accurate. Those seem like an odd profile of bullet for your 45 acp. Maybe they are sized for the 45 Colt at .452-.453", that may also explain why the crimp looks heavy even when it's not.

    They are an odd bullet but they're sized at .452 like the rest of the Berry's .45 caliber bullets they have listed under their .45 ACP section. Seems many use them in .45 ACP.

    From what I understand, .452 is what I want in plated or lead for .45 ACP. That would help explain the crimp though. Thanks for that.

    I haven't started branching out to other bullets yet

    Crimping is weird. I loaded up a batch of .44 mags with no cannelure, and the bullets walked out. Since then, any high pressure pistol round only gets bullets with a cannelure. Wadcutters need a bunch of crimp. I never crimp rifle rounds.
