Too bad. Here is what I came up with 3.9 grains of CFE pistol powder using a Missouri hard cast 105 grain seated 1.050.Shot great out of the STI and PPC9. the Hi-Tek coating shot tightest. I did not chrono it yet. When I do will give you feedback. Hopefully will be able to get out tomorrow.
Burn rate just above V3N37 and N350 for reference.
Do you have the factory spring in your STI? Little surprised that it did not work the slide for you. What other powders do you have access to?
Cant get these lighter bullets to shoot worth a poop yet out of my .38 yet.
Thanks for the reply to my inquiry.
