I'm new to the Ak-47 and just purchased a Romanian WASR 10/63 and got 2 tapco mags with it. I got some Winchester ammo and went out to shoot it and when i pull the bolt back to put the ammo in, it goes in the barrel but the bolt does not catch the ammo on the extractor and the bolt will not close fully. Hope this is not confusing i am trying to explain it the best i can. What would be the problem? Can the bolt be installed wrong? Anybody have any suggestions.
