You said “I really want this bullet to work” so what’s not working? Is this affecting your accuracy, function or just messing with you mind? I run the exact same set up. Dillon 650 all factory dies with the exception of a horanady neck expander. I find the bullet sits better before seating with that die. 165 xtreme mixed brass, win primers and 3.8 gr TG. Set to COL of 1.157. My experience with this shows a range of 1.149 to 1.17. But every one feeds and goes bang just like the last. I run them primarily out of my STI but have also shot them in my G34 and my PSA PCC. Never any issues. So unless you are have issues with feeding or some really bad accuracy just feed the Blue machine and fire them off. Sent from my iPhone using Tapatalk
