update on this issue,
I had a remington come in the shop last week, that displays the same issue. after inspecting the hood, upper locking lugs, barrel bushing and lower lug bearing surfaces this is what I have found.
The lower lugs are not relieved to prevent (barrel bump) which causes the cross pin to have to overcome the lower lugs, like a pinch point.
I add some extra relief to the barrel bushing at 12 and 6, rounded all the barrels 90 degree counters and recut the lower lugs.
I also added the correct Vertical impact surface recess, corrected the feed ramp angle,width and depth, corrected the barrel throat angle, and reset the chamber depth to .906.
problem solved.
Cost. 145.00
