    I've seen it before, but it still looks pretty cool. I'd be interested in what kind of velocities and expansion they get. Being brass jacketed, like Montana Gold's, I'd be willing to bet that they will produce lower velocities than copper jacketed bullets like XTP's.

    I love the idea but something smells.

    1. The 9mm case is too small (not 40 cal).
    2. We have before and after pics. What about the steps in between? Only 1 step?

    Here is a pick of expansion, after being fired into wet newspaper.

    finally, a decent use for the 9mm!

    Was there any mention of accuracy?
     
  9. Yes!!! I've been looking for something worthwhile about this round for a long time!

    I want to see Grissom figure this one out.

    Bonus points if he identifies both guns in less than an hour.:supergrin:

    LOL...good one!
    Better than a 380,
    380 better than 32,
    32 betterr than 25
    25 better than.......

    That is really neat, there are some bullet making companies where you can buy the equipment for making your own swaged bullets from lead wire and 22 cases, for the 223
    never had seen this before but wow, with price of bullets and all had seen the equipment for 223 cases made from 22lrs http://www.corbins.com/kit-224.htm

    ck this out from their site re the brass-
    Rimfire jackets are only about .010-.012 inches thick, made of 70% copper and 30% zinc. Most commercial jackets are around .018-.022 inches thick, and are made of 5% to 10% zinc with the balance copper. These two facts lower the friction of the rimfire jacket, so that it is actually easier on the barrel than a commercial jacket. Zinc lowers the co-efficient of friction, and the thin jacket engraves easier by the rifling. (Higher copper content alloys do not break up on impact as much as the rimfire cases, so they make better bullets for edible and dangerous game hunting. Rimfire cases tend to break up when they hit the ground, so they make better varmint bullets with far less richochet potential.)

    Curious what the typical content of metals in the average 9mm case is
