Larry's Guns/Red Feather Hammerli Scope Mount Reliability issues

Toonces wrote:I had one instance of that with my new 208s in 1998.  As instructed by Larry (RIP), I shortened the tabs on my magazines (the bottom part that contacts the mag release) to lower the magazine in the gun, so an empty shell held by the extractor now clears the rounds in the magazine.  It didn't take much, maybe 0.010 - 0.020".  This ensures the empty case hits the ejector properly and goes to the side, instead of hitting the next round in the magazine and going up.

Perform at your own risk, it's easier to remove metal than put it back on.  I used an extra-fine file, and it didn't take many swipes.  

I also cut my mount the way your are describing, because I really hate alibis.  After both modifications I went through a case of CCI Standard without any jams/alibis/misfires.

Here is an empty over a loaded round.  There should be zero movement of the case until it hits the ejector.  You will see a wiggle if it's hitting anything before the ejector.



This shows how close the magazine is to the bottom of the ejector.  It was pretty much touching before trimming the magazine tab.  There is maybe 0.020" of clearance.


This shows the trimmed magazine tab.


This shows my mount and ring after removing the material over the slide.

I bought my Marvel conversion in 2001 and was also having similar issues.  While at Camp Perry I met Bob Marvel and described the problem.  He said, "cut that top rail flush with the breech face and polish it.  THAT ended the stovepipe/trapped brass issue completely!

After several hundred thousand rounds with various ammo I never again had that problem.

I suggest you consider modifying that mount accordingly.

What is the proper way to remove it to clean the gun..meaning do you remove the four small countersunk screws or loosen the clamp on dovetail for the weight? When I unscrew the the 2 screws for the bottom dove tail I cannot slide it forward far enough for removal.
