I need some advice, I am trying to cast for the 450BM but am having feeding issues, I cast for a lot of calibers but this one still haunts me, I am shooting with AR style, I can load Flex tip, FTX, Deep Curl, 330gn cast HP, but I can not get it to feed 235gn cast RN, 250gn RN, or 300gn FP. I have played with the seating depth and bullet size, am I barking at the moon here or doing something wrong any help would save me and my checkbook a lot of heartache.
