Pearce did a great write up on reloading for the .40 S&W. All loads were developed/tested in a G22.
He covers unsupported cases, cast bullets in the Glock barrel, etc.
It has a lot of good info in that one article. And a schit ton of load data.

These days there is no better writer out their than Pierce IMO. No whining about what others say or believe. Just the facts as he demonstrates them. I just bought the issue yesterday. His work is always thorough to say the least.
