Deeangeo, I have a Greek 1903 action only which has identically the same feeding problem even with brand new brass and the correct 160 grain round nose soft nose bullets. The case hits that lip and jams up solid. The action has been dicked with by someone else before me and I have to sit down and work out why this is happening. I have a model 1910 in 9.5 x 57 MS which feeds perfectly with round nose bullets as well as pointed soft points, but I can not get that 1903 to feed regardless of the bullet seating depth. If I get a chance I will try to sort it out and let you know.
