I came down on the aftermarket side of the "shoot lead in Glock barrels" debate so I am now using a KKM barrel with the same bullet.

I think the trick is to have just a few thousandths of the lead driving band exposed at the case mouth - it's hard to measure accurately but I come up with somewhere around 0.020".

Having a bit of lead exposed makes a sort of soft ramp for the ejecting case to ride on and helps, in my opinion, to prevent stovepipes.

But, yes, try a few before ordering multiple thousands. That the bullet is 100% reliable for me is no guarantee that it will work in any other gun. But it is 100% reliable...


That's great. Many people have issues with SWC in a G30. Even my G34 is not 100% with a 9mm that has a forward driving band. Why risk the issue. He wants simple. Pick a TC or RN.
