Well I got home this afternoon and did what shooters told me to do as far as chambering a fully processed 243 brass. It chambered and the bolt operated just as smooth as could be so I took a bullet seated it a tiny bit at the time til I got just under max coal and just like all the times before the bolt was difficult to lock and release. I got to looking at my brass and noticed about a quater of an inch from the bottom on the side of the body of the brass there is a ring around all of my cases that I've fl resized and seated a bullet in and some of them are way more not icicle than others and on a couple I ran my fingernail over them and if feels kinds like it's slightly bulged out where the ring is.
