It'd be nice to try one out before I took the leap. I'm thinking once this kind of a mod was done to the action, if it didn't work as advertised, you're pretty well screwed for using it as a repeater.
Here is rifle back today using Wyatt's CFE. Still working on tweaking to get more than one round to feed realiably. When have two in magazine it causes 1st round to not feed right. Any pointers appreciated.
Don't know if this will help your feeding issue, but I recall watching a video on Wyatt's site that talked about heel pressure on the follower and having to change the heel pressure to make things feed right. May not apply to your application, just a thought.
