I have Quickload 3.8, and recently went shooting my 357 Sig with some 125 grain Speer bullets loaded to normal length (1.140") using 13.5 grains of AA-9 powder. The primers looked pretty flat, so I was thinking of reducing the load, but when I ran the fired cases through the GR-x push-through die they went through with no big deal. This is in contrast to some 40 S&W and .357 cases where you just about have to sit on the press handle to shove them through. ????
Then I decided to try the max load for 357 Sig using AA#9 (14.6 grains with a Speer 125 grain bullet meant for the 357 Sig) in Quickload, and I got a pressure of 78,000 PSI and a velocity of 1722 FPS. YOW!! Referred back to my chrono notes, and it turns out I had fired this load in my P226 Sig and it chronoed out at 1450 FPS, which agreed with the loading manual. Have tried some data using AA#7 powder, and have pretty much gotten the same hideously high numbers.
Tried a max load of 11.0 grains of Blue Dot (Compressed) and the numbers that came out were safe and agreed with the manual pretty closely. Same for VV3N37 powder. Anybody ever have this happen with AA powders in loads they looked at in Quickload??
