Where do you find steel bullets?
The Russians and Chinese load "bimetal" ammo that is somewhat magnetic
but it is not really "steel". I tore down a "Brown Bear" 9mm a week or
so ago and the jacket is not really that hard. I also posted a link to
a 10,000 round test where they showed that it cuts barrel life in half
(5000 rounds vs 10,000 in the .223s they tested). When they factored
in the price of a barrel against the savings on ammo, it was a wash. I
imagine the effect is less in a slower round.

If you trade in guns as fast as Harry does, I doubt he would ever
notice.

So the jacket material doesn't protect the barrel? I must be there to
make it feed better or to keep the steel from corroding.
