Good to hear you got it going. I have an early LM7 that interestingly enough couldn't get to run on FA until I put a Razorback bolt in it. As others mentioned and you found out bullet seating depth and especially belts that are loosened up are key. Also, never could get mine to run on anything but CCI mini mags. One thing you also might consider along with posting on this board is the lakeside forums located here...Thanks everyone for the suggestions. Seating depth in the belts was the cure! Only a couple stops, more than likely due to a couple tight belt pockets. I didn't have any blazer to try but it definitely preferred CCI over federal.
