Remington went bankrupt for a good reason. Their QC was terrible for many years. I had some Remington Express 7x64 ammunition that looked just like that. And had reports of others with the same problem. Before I retired, I was a sales consultant for an engineering firm. I have some personal knowledge of high speed automated factory production processes. Properly designed equipment doesn't do that. Ever. And any automated equipment line should include an optical flaw detection system to cull out any "accidents" of a much more minor nature. In my opinion, there is NO excuse for that kind of flaw other than sloppy manufacturing and bad production line design. But Remington's motto seemed to be, advertise a lot, produce everything possible as quick and cheap as possible, and if there's enough complaints about defects and flaws, rely on "warranty".
I strongly prefer the quality of European ammunition. I have never once encountered or heard of a serious QC issue with Norma, RWS, Lapua, or even relatively cheap S&B ammunition.
