I have found that not all Grendel bolts are equal. I measured the inside of the bolt from the tail to the back side of the bolt head on my new AA bolt and Satern bolt and they matched. Then I measured a BCA 6.5 Grendel bolt I got on sale and the inside measurement is .080" longer so the bolt head on the BCA bolt is .080 thinner. A .223 bolt measured the same as the BCA bolt. I suspect the BCA bolt was made from a .223 bolt blank. You get what you pay.
