Good luck, I am having the same problem with a 6x45 model 11. Hollow point bullets are the worst. I have 3 magazines that have fed every spitzer style bullet great. Move up to the sierra 75 hp and 2 feed 1 doesn't. Move to the sierra 85hpbt none will feed! I HAVE CHANGED SEATING DEPTHS BY OVER .100" NO LUCK. Some say bend the feed lips ,That didn't work for me. The magazine feed lips need to be 1/32"
longer and I feel this problem could be solved .try a different style bullet
