frustrated and annoyed

So I switched all my brass over to a new batch of Starline. Previously I had a load of 26.8gr of imr8208xbr that was pushing 123gr SST at 2325ish fps. It showed no pressure signs in the hornady brass or in a few starline pieces I had then.

Did a new ladder with the 10 shot method and found a node b/t 27.7-28.3 at 2380fps. None of those pieces had pressure signs.

I loaded up at 27.8 with a base to ogive of 1.653" and shot one of the best groups the gun has ever shot.





I got super excited and then looked at the brass, slight ejector swipes and extractor marks :mad:





I had some loaded with the old load of 26.8gr into my new batch of Starline and now I'm getting 2250fps and seeing ejector swipes and extractor marks on random pieces with those as well.

I refuse to believe I can be that much over pressure with such low velocities. Am I crazy or is there another explanation?
