Sir, there are several different 17 hornets, the most common being the 17AH. My 17 hornet is not a true 17 AH but a modification of it. There is a true 17 hornet that is the hornet case necked to 17 caliber without the shoulder being blown out. Dave Kiff at Pacific Tool makes the reamer for it. It looks like like a 17 AH before it is fire formed. Anytime the 17 hornet is talked about it is usually the 17 K or 17 AH, one has a 30 degree shoulder, the other a 35 degree shoulder. I have only known of one true 17 hornet with out the case being blown out, that was years ago, and the old man that had it built it himself.
