Well after some trial and error I got the 16-40 working, I changed the recoil spring to a 14 LB which corrected the feeding problem, then it would not eject, I removed the power extractor and the spring in it was very heavy, the extractor would hardly move, after trying several springs I found one that worked, it now functions very well, now I'm trying several .40 loads and bullet weights to see what works best. I talked to several shooters that load the .40 S&W to 1.225" OAL, but they have machined the chamber to allow this, I loaded some 1.150" OAL but have not tried them yet, it feeds 180 grain 1.130"-1.135" OAL very well.
Thanks
