I just fired my first couple 40Super rounds out of a 1911/Storm Lake barrel that I just completed the fitting on.I have a 24lb recoil spring and the firing pin spring is a sronger than factory, but I can't find my notes on what poundage.I do have a small radious FPS in it,and a19lb hammer spring.
The primer strikes were normal on the 45ACP loads, and the rounds I fired today are Double Tap 200gr FMJ and they are pretty stiff,but recoil wasn't bad at all(I think my 357Sig in my XDM are about equal),I was surprized by this,The brass flew about 10 feet behind and to the right.Overall it ran fine,I hit a 6inch gong standing and nervous(not really trying hard to aim good and trying to watch where the brass flew) with all three shots at 20yrds.
The primers have no dimple,and the firing pin you can see actually was digging into the primer and scraping the plating off.What changes need to be made to solve this,it will probably break the firing pin or pierce a primer eventually.
When I reload them I'm going to use rifle primers(I don't know if DT used them or not in these)and I am getting Starline brass with the small primers to stop primer flow(which is what I think is happening here)
