which gauge did you use to measure the Datum on you Cooper Creek Modified Case. Did you use the Hornady or the Forster.
I have a Forster and my case measured 1.185. the OAL is same as your measured.
Those are the numbers for factory ammo and my full length resized as well. I am going to try and bump the shoulder less next time I reload and see if it cycles. My fired brass is measuring 1.190-1.191. I really only want to bump it .002-.003, I've been bumping .007, way to much for my liking.
Ideally you want to use a modified case that has been fired in your chamber. You can make your own gauge, but you need a specialized tap. It is a 5/16X34 and a #7 drill bit
