Gunsmithing Bighorn Origin feeding question

[rootacres]

Hey all,

So I am using a bighorn origin on my 7mm wsm. Here is my question/issue. When picking up a round out of the mag and control round feeding into the chamber everything is great. If I was to single feed a round or if for some reason when chambering a round the case gets in front of the extractor and bolt face the bolt won’t cam over when trying to closes and I can’t extract the round. What could my issue be or is this just how the control round feed works on this action?

It should cam over. Call Zermatt and see if they have a recommendation, it may be as simple as lightly stoning the extractor claw. But that could cause a frequent failure issue if too much is removed.

havent had that issue with any zermatt action in multiple sizes

I've only seen it on some mausingfields with that massive extractor but a little polish fixes it

Clean the extractor.
Sounds like it's not shifting to the side when you chamber the round.
Remove it inside a ziplock and clean it, then reinstall.
