Sorry for my ignorance, but isn’t the AI magazine aftermarket? Your problem may be with the magazine and not the rifle. What kind of problems did you have?
Factory ammo CAN be over pressure, but seeing the brass would also help to know if it was possibly a burr or something else causing the problem. She can send it back to Ruger for warranty repair if she tries different ammo and the problem persists.
I had a savage that had a slightly (almost imperceptively) proud action screw that caused these same symptoms. A few seconds on the grinding wheel cured the issue.
It came with the Ruger American Go Wild Package.
What don't you like about the Ruger rotary magazines? Would you make the same complaint about the Browning X-bolt magazines?
They don't feed reliably. I've been through 4 of them, of which one seems to work well. The other 3 have weak spring pressure on the follower or the rounds hang up inside the magazine. I've started to use the magazines for the 450 Bushmaster with 7mm-08 rounds. It will hold 3 rounds and is single stack, and seems to feed more reliably. However, it does stick out of the stock an inch or so. For $40 each per magazine, Ruger should be able to come up with something that functions.
Same issue with my 308 especially in cold temps. Learned the hard way in October. Would not pick up a round
It might just be a short chamber, driving pressure up to cause it to stick, but most likely it's just a rough chamber that needs to be polished. She should get in touch with Ruger and have them take care of it. Their customer service has a great reputation.
Have had this issue with an Axis 2 and Hornady loads (Superformance, 7mm-08, 139 grain). In my case seems I had a bad batch of factory ammo as the primers were blowing out of the back end of the case and causing ejection issues. Used some Federals with Accubonds and no issues.
