9mm powder charges

[ArchAngelCD]

There are a few powders that are sensitive to case volume sizes, TG is one of them. TG blew up a lot of guns early on before this became widely know. The cause was traced back to bullet setback in both 9mm an 40cal with these being high pressure rounds. Lyman even mentions this in their hand loading book, saying 0.050"? (maybe less) can double the pressure if at max load.

I won't use TG in any of my guns. Saving a few pennies on powder isn't worth blowing up a $700+ gun. I have seen way too many handguns blow up to use that powder. Granted most were 40 S&W but I did see a 9mm blow up too.

Don t get me wrong, I'm not saying others should not use it and many loaders do safely, it's just not for me.
