One grain too much H110

No good data and I made some calculations. The SWC 210 ran 1875 fps and seemed good except for pretty flat primers. However a simple change of bullet design, to a Tumble Lube LEE 210 gr. caused mildly pierced primers, the gas ran around the extractor notch in the bolt face too and gas stained the cases. I noted some greater fps variations and speed was lower at 1800 fps avg. No harm but I know lots more than I did now. They shot accurately and no other case deformation. Primers were WLP Mag.
