My Kimber 9 mm 1911 will not feed FP bullets reliably so it is RN all the way. I have messed arouind with different seating depths but it simply will not improve.

My Tanfoglio P19 CZ75alike has minimal rifling lead. 124 gn RN can get stuck in the rifling with the RN unless set deeper into the case. FP bullets, which are shorter in length, feed reliably and always chamber properly.
