The action does not cycle after I shoot it. I shot 1 box of 50 and it cycled 1 time only. On rare occasions it would stove pipe, or half eject. Normally, the empy would still be in the chamber because it didnt cycle the action far enough to remove it. The extractor does grab the shell. The rifle has about 300 rounds through it since new and worked fine when it went in. I was wondering about springs etc.
