6 arc gasser

I was getting set up to resize some 6 ARC brass that is once fired in my rifle. Brass used was Starline. Fired brass from my rifle is measuring 1.191 using Hornady Headspace comparator and non fired brass is measuring 1.181 using headspace comparator.

That seams excessive to me but I’m by no means an experienced reloader. Is that amount of shoulder movement normal or okay?

Barrel is pretty accurate. Shot .68 for 10 shot group at 100
