Having some issues with a seating die. I can get a COL within spec, but only by a couple of mm. Max is 73.8 with the slightest of neck contact from the die and the seating insert wound right out. I am aiming for more like 76mm.
Anyone ever have this problem before and found a simple solution? I'm thinking the easiest option may be to machine off a couple of mm from the seating insert?
