I have a blank and bolt for a Stiller 375 CheyTac action, the bolt came from PTG originally, but I bought it from the buyer who is an acquaintance.

PTG used to sell the action, but I don't see it listed on their website anymore. Stiller now sells the action on their site, and they list a 1.45" diameter action and a 1.60" diameter action. I'm not using a tube though, I'm using a tactical stainless, and it's big, I need to mill a lot off of it, since square things don't work well in the lathe, at least not in the beginning they don't. I'm not that patient and this blank has been heat treated after it was EDM'd.

On the Stiller site they show the 1.60" with a .747" bolt, and I have a .750" bolt. On the 1.45" spec, it states .750" with either a 1.45 or 1.60 diameter action.

I think I can figure it out by knowing the length as the tenon and I am not working on this just yet. I have sent a message to PTG to ask if they would share the blueprint they used, as it is their bolt. Not sure if they will or not just yet. Any comments? Please be easy on me, I'm just a DIY gunsmith, and only play one on the Internet. I mean no harm.
