A note on crimping and plated bullets. Not saying this is good advice or bad advice, just reporting what I do. I roll crimp every 38 special I make, even plated bullets. Below is my usual 38 special load which is a 125 gr Berry's flat point. As you can see from the pulled bullet on the right it is heavily crimped. I've shot thousands of these and never seen any detrimental effect from doing it this way. I've even shot them into poplar logs and bags of wood pellets and the plating is still intact when recovered.
Same here. I might crimp a little less than you show, but I roll crimp plated bullets. I, too, have recovered some fired bullets and been impressed that the crimp line doesn't seem to have done anything to compromise the plating fore or aft of it. In fairness, I am not a bullseye-grade-accuracy shooter, and it's possible there's some very small diminution in accuracy that I am unable to detect due to my skill limitations.
