Lapua Brass. Dunno about the throat, reamer only says .308 match, but it is pretty short. I got the reamer from an old BR shooter and gun smith Don Geraci. He gave it to me and a couple of PPC reamers to practice chambering. Darn thing cuts so good, and every gun has shot so well, I am not changing. I have used a throating reamer on a couple of 308s to create long throated chambers just experimenting, they shot pretty well also.

4 shots from the first rifle I ever chambered with that reamer from 1K
