Kinda thinking along the lines of M-1 enbloc first round friction then the rest feed easy. Op rod forward assist first round. If you load the enbloc with the last round to the left it’s difficult to insert the clip in the receiver. If the last round is loaded in the enbloc to the right, it’s much easier to load in the receiver.

I agree to focus on follower and spring but also consider the receiver rails. Maybe a little rough? What does the brass look like after you load it?
