I have picked up my second Savage rifle [first was a Savage .22 semi-auto]. This .270 has had a little work done to it [Timney trigger, Falcon scope & Choate stock]. I wanted to get the date of manufacture. It's an H621xxx serial number. The Savage website part finder does not date the build at all, all I got was a parts diagram. After searching for an hour I found this site, so I thought I'd ask if anyone knows about the serial number sequence enough to get the year of the build? Any info would be helpful....thanks!
