I bought a brand new SA Champion GI and bought some Wilson 47D mags. I went to the range with abox of the Winchester white box and it fed perfectly and shot just fine.
I got home that night and ordered some CMC 10 RD Power mags. When I got them I went back to the range but bought a box of cheap Blazer ammo. I loaded the mag up and inserted it. When I racked the slide, the first round would jam up and not chamber. If I dropped the jammed round out, the next would not ramp either. It seemed to finally load the 3rd or 4th round just fine and ran great for the rest of the mag-load.
I also tried it with the Wilson 47D that previously ran flawlessly with the WWB ammo and it jammed the first few rounds as well with the blazer ammo.
I haven't tried the WWB with the CMC 10 rounders yet though.
