Friend brought out his 47 X1 to the range this weekend and shot it for the first time.  Shooting brass cased ammo, it worked flawlessly for the first ten rounds out of the RRA mag.  After that it would eject the spent round fine but wouldn't pick the next round up from the magazine.

We tried an eastern European mag with both brass and steel cased rounds with the same result.


Switching back to the RRA mag, it would hand cycle a complete magazine full.  Thinking it was working again, chambered a round, fired and ejected fine but failed to pick up the next round off the mag.


Friend called RRA today and was told the chamber was dirty and needed to be cleaned.   Horse hockey... Ten rounds from new is a dirty chamber?  And how would a dirty chamber cause the bolt to not even strip the next round?


Need some common sense help Steve!   Thanks.

if it were just the one mag, I would attribute it to a weak spring in the mag and go from there.  That it's occurring with two mags makes me wonder.
Are you getting a full cycle, or is it giving you a "bolt over" in which the round fires, but the bolt is only moving rearward far enough to kick out the empty but not far enough to strip off the next round?
If you let the rifle sit, will it start to fire off the mag again, or is it consistent?  Is it always the 11th round when it starts acting up?
I'm going to need a lot more detail to try to diagnose it from a distance.
Thanks.
Steve/RRA

Steve, we believe it is a bolt-over issue.  Number of rounds in the mag doesn't matter.  And we tried three mags with brass and steel case ammo.  BJ@RRA said to clean the chamber...

The preference is to send the rifle back to Colona for the experts to take a look.
