I did some investigation and figured out why the beltfed was having some issues . Its a link issue. Most of that ammo I linked up 8 years ago when I bought 5,000 links from Old Sarge's Drop Zone. The links take some prep work before use that I wasn't aware of 8 years ago. I had a friend show me that you need to tumble them in corncob media to smooth some of the park finish down and then give them a coating of aerosol lube like Hornady Oneshot . He now has 100% function following that procedure. Some of you who left early missed out on the local leo showing up because of a report of machinegun fire. It was pretty funny, Moosedaddy continues to fire even after the guy pulls up to talk to us.
