I've had some issues with dropped shells. Seems to be fine after a full tear down cleaning of the bolt head. The extractor was probably not seated properly. Funniest part is I had more touble with Hornady then with Tulammo. Tul is just too dirty for me. 10 rounds of it is worse then 100 of AmericanEagle FMJ or Federal FMJ Trainers. Must have the graphite coated powder or something. The coating on the cases seems to build up on the bolt head as well.
