[QUOTE="AtownBcat, post: 648494, member: 15385"] Ok I have taken a few measurements (with pictures...I know how you guys like pictures) The first is for the neck measurements. I read 5 fired cases and they all read the same so I zeroed on one of them and here is what I got: [IMG]http://i689.photobucket.com/albums/vv252/Atownbcat/3bb116b7.jpg[/IMG] Next I have an innovative technologies bad *** headspace guage. Looks like I have exactly .006 clearance between new brass before it is fired. [IMG]http://i689.photobucket.com/albums/vv252/Atownbcat/e6a7436b.jpg[/IMG] And finially I have pictures of the case heads. It is not easy to get the swipe to photograph y but you can see the circle. First(right to left) 36g 2000MR....2577fps 39.5g 2000mr......2760 41.5g 2000MR......2942 [IMG]http://i689.photobucket.com/albums/vv252/Atownbcat/846dcbbb.jpg[/IMG] I do realize that solvent and or lube can cause problems but this is not what's going on here. Also the rifle has been cleaned by the letter of the law...no copper build up or other cleaning related issues. Notice in the pictures the primers do not really show any issues...but with circles and heavy bolt(but like I mentioned slightly heavy on the close) it has me confused... [/QUOTE]
