I installed a 1.5# Jard trigger on my New Haven Model 70 Coyote Light. Followed instructions, everything went OK but I was never able to remove all the creep without having the gun not cock if I vigorously operated the bolt. Sent the trigger to Jard, they polished it (not sure where) & didn't find anything wrong with it. Still the same problem - if I try to get out all the creep the gun will not reliably cock. Anyone seen anything like this? Any ideas?
