Went to the club to try out some 223 loads and something weird happened. First off, the rifle is a Sako L461 with a Wilson barrel. My loads were CFE 223 powder,Fed 205M primers in Winchester brass trimmed to 1.750. I had 4 different loads, 5 each, starting at 26.5 grains. The first two shots seemed normal. Fired fine, extracted fine and ejected fine. Third shot seemed normal, went into the group but when I tried to eject it, it seemed to be stuck. Of course I left my cleaning rod at home so my trip was over. Three shots and I'm done. Got home and use a cleaning rod to eject the case and all looked fine except the primer. It had what looked to be almost pierced but not quite. Very deep but not pierced completely. I chambered the two previous rounds and they ejected fine but when I tried the one that stuck I had to use a rod to tap it out again. I measure the bad round and compared it to the two previous rounds and found nothing different. I chambered several resized cases and all was fine. I went back to the range today and fired two more of the 26.5 loaded rounds and they were fine as well. What the heck is going on? My other three loads go up a half grain from 26.5 to 28 grains. I didn't get to shoot them today, maybe tomorrow depending on the weather. I thought the extractor took a dump and finding one of those for an L461 is near impossible. I'm hoping it was just a fluke but won't know until another range trip.
