[QUOTE="Dean2, post: 2777507, member: 26077"] I have followed this thread from the start. I intentionally did not post earlier. I was NOT trying to beat on you or be condescending when I made the comments I did. You have admitted the errors you made so there is no point in berating you and you owe no further mia culpas. My point was, pushing over published velocities for a 75 grain Cup and Core by a lot, and over published load weights for 4955 for an only slightly heavier projectile means you are over max pressure. You were at max at 49, over at 50 and way over at 51. How over pressure shows up varies greatly for many reasons, not the least of which is the gun used. There has been a ton written about primers and ejector marks NOT being reliable indicators of pressure. However, blown primer pockets are every time. You are free to believe the powder is the problem but you are wrong. No matter how often you have gotten lucky using your specified loading practices, it is just luck, certainly not skill. The one fair conclusion you could draw from your experience with 4955 is the one you have already stated, learn and significantly change your loading practices, I think that is a great and fair take away.
