i was cleaning my Sako AV after another successful season, and removed the bolt completely to clean it. this bolt has some moving parts, and I can't seem to get itback in properly. I can get it back in past the bolt release,and about 3/4ths closed. there is a slot in the reciever where the firing pin mechanism slides into, but the pin isn't lining up with the groove in the stock by the safety. any Suggestions before I have to take it to the gun shop?? Thanks!
