I was at the range today and my trigger locked up when i closed the bolt. I know that if the trigger is set too light and you jam the bolt closed the accutrigger will lock the sear. However it did not matter how hard or soft i closed the bolt the trigger still locked up. The only way i could get it to function correctly was to push the bolt forward pretty hard (hard enough i needed my support hand to push the rifle back into my shoulder.) It made no difference weather a round was in the chamber or not. I have run about 300 rounds through this rifle and never had a problem. any ideas?
