    This by chance is not a Bartlien and a speedup pushed the load over the top?
    For a laugh, why did you not ask this in the hide?

    It's actually a Krieger barrel and im wondering if that isn't the issue.

    The funny thing is, it was an autocorrect mistake but before I got to go back and correct it and post a more detailed response along with an apology, I was banned lol. Not too worried about it though, I had a pretty good laugh over it. Lowlight ended up as lowlife. Shit happens and I haven't lost any sleep over it.

    Ok,
    My idea might not be something in your case, but it was worth a try. A few years ago, I was changing Hornet rifles. I was using all existing components (same lots even) in working up new loads for the new rifles. I was experiencing pierced primers even though I started from lower level charges of powder and worked back up. I was experiencing the pierced primers with even the lower charges in both rifles. I could not at all figure how that could happen. I was using partial full length resized brass from the first rifle that dropped right into the other two. For some reason, I fully resized the brass and suddenly, primer piercing stopped. I don't know why it happened, just that the brass was the culprit.

    I checked trim length and they are good. Loaded neck diameter has .004" clearance in the chamber I have. Everything seems good. I had a member suggest that I color a dummy round with a sharpie to see if it had rub marks on the ogive to see if it is rubbing a carbon ring. No marks when I checked so that has me leaning towards just needing to back the powder charge off from the barrel speeding up. I dropped a grain and a half to see where I'm at with that but I also loaded some lighter to work up to that to see if I have any pressure before that point.

    I'm guessing the speed up was the issue. I'm backed off 1.5 grains and am about 30 fps slower than my original load to get back down to no pressure signs. Sucks that a 6.5 saum is under 3000 fps to get back to a safe load again but as long as it shoots as good as the original load, it won't matter.
