[QUOTE="Sackett, post: 535320, member: 35172"] OK I've got a major problem or to me it is!! Last hunting season I noticed that some of my brass was cracking (or showing a ring) just above the belt on my 7mmRemMag. I've never noticed this before and have been shooting this load for years. It is 66grs IMR 4350, 140 Nosler Ballistic Tips, 250 CCI Mag primers. My uncle started this load way before I started loading...I just kept up this load as it had performed well. Anyway I thought that my brass was getting worn out, so I replaced it with new Winchester brass the other day, when I shot it today,,dang!! same thing>.I looked it all up and rechecked my dies to be sure that I had resized the new brass correctly, by full sizing I did,,,I even readjusted my dies, still same thing even with only 60grs of powder!! Now, it was not as bad at 60grs but the "RING" was there!! The only thing that I can find on this topic is in an OLD reloading book, there is a picture of the same thing that is happening to me, it says that if it ain't a head space problem then it is a sprung bolt,,,,that the bolt will let it have enough "slack" to cause this???? Can anyone help me out here???? I know that it ain't a head space problem,,,I've redone everything!! Thanks in advance~!! Shawn aka "Sackett" [/QUOTE]
