Was at the range today and witnessed a relatively new shooter having a heck of a time with FTE using South African M193. This was the newer stuff being imported in the 50 round boxes in 200 round sealed packs. The fired cases had to be removed with a cleaning rod and we founf that the extractor was ripping the rim off the case. What was weird was the fired cases looked clean and so did the chamber on inspection. I gave the guy a couple boxes of Federal XM193 I had and he ran all 40 rounds through with no issues,

Thoughts?
