As for the rifle it is a Savage Mdl 64 with a very different barrel that has a smaller bore than usual. Instead of being .215 on the lands like both of my Marlins it is .200 flat. Since most of you probly know more about barrels than I do, can you tell me if this is good or bad? By any means it is the most accurate 22 I have shot or owned and deffinately the most unique sounding. When standing to the side its sounds as if the bullet is zinging which at first made me believe the bullet was tumbling in flight, but there are no signs of that at any range.
Ok, some questions.
The Savage Model 64 is actually an Anschutz Model 64 that Savage used to import. I worked at the Anschutz National Service Center for three years as a gunmaker building nothing but competitive rifles for olympic, international, and NRA smallbore.
The minimum bore dimension that SAAMI specifies on a rimfire barrel is .215 if I'm not mistaken (don't have my reference book in front of me right now). A "tight" bore is considered a .2155-.216. This is what most of the premium barrel makers run at and some (like Anschutz) put a slight choke on the last inch of so of the barrel on the muzzle end. It seems to help accuracy.
A .2 bore ID says to me you are essentially turning a .22LR into a .20LR That's just not quite adding up so I encourage you to check your gauging or your procedure a bit and try again.
The tightest bore I've ever worked on was while as the production manager at Nesika Bay Precision/Dakota Arms, Inc. We had a string of Walther barrels that measured .212" I had to have special floating pilots made because my reamer wouldn't even fit in the bore. The barrels were horrible in performance and we ended up pulling them and going to something else. These were on the little 22's that Dakota used to produce.
I'd like to see a photo of the rifle and the crown of your gun.
