Dillon 650. I thought they were below flush, but was told by an experienced shooter, they might not be recessed enough. I'm fairly new to reloading, so I only can go off what I'm told. Everything I've loaded so far (around 5k rounds) goes bang. Coincidentally, I should've mentioned I've been having issues with my primer wheel on my 650. It over rotates periodically in one spot, and needs to be manually rotated clockwise a slight amount until it clicks. The primers still seat just fine or so I thought. I really make sure to seat the primers hard. Can I adjust the primer seating depth on a 650?
