Am loading bullets for fire-lapping my Marlin .444 and am having just a little trouble. I feed them singly and when closing the lever it takes quite a bit of pressure the last half inch of travel. I note that there seems to be a bulge where the bullet is seating in the case. Is this typical fore these bullets? They were purchased from Beartooth. The cases have been resized, trimmed, crimped. What am I doing wrong? Thanks-Karl
