A while back i modified my AI mag for my SAUM by removing the front plate. Up until yesterday i had been load by hand. I wantrd to do a seating depth test starting .005 of the lands. I then realized the tips of my bullets were catching the underside of the feed ramp on my action when I clipped the mag in. I after I had calmed down from frustration. I tried calling my smith but could get through so decided to have a go myself. I lined up the mag and marked the ramp with a pen. Then used a new chainsaw file through the mag well while running a vacuum nosel in the ejection port to catch the filings. I finish with 800grit wet n dry. 25min job done!
