I recently purchased an older savage 110 long action chambered in 243 as the start of a budget build. I like to know the history of all my firearms and I contacted savage to find out more. Serial number F544xxx. They informed me that it was a model 10 GXP chambered in 243. I understand that this could have been sold as a package set up but how can it be a short action if the receiver screw spacing is 5 inches. The answer is it probably can't. Just wondering if anyone has any more information on this question. I'm really just trying to find out some more information like shank size which I believe is small, and twist rate of the existing sporter barrel. I don't have my gun barrel vise yet so I haven't been able to get an accurate measurement to determine shank size.
Im a new member and I've tried to search for any possible existing answer in the posts so please have mercy on me if I missed it.
