the 7.62x39 is a stand out for the .303 british.

That reminds me...the 7.62x39 is a .311" bore not .308" like the 300 Savage.
Thanks, Dinny
BINGO!!!  Of coarse you could still do it and have a .311 Savage  but factory ammo would likely be woefully in accurate.
 but factory ammo would likely be woefully in accurate. 
If you must have one the 300 BLK or a stub job is about your only option...  The 300 blk would have a pretty short barrel tho...
Personally I would have a stub done.

Tried a bullet in the muzzle and tight as it was I believe the .300 Sav. would work.These &.62 handis must not be .311 inna bore 

 .Looked at the sight Dinny suggested, and I believe it would be an easy conversion...
However me Old granny always taught me to listen and respect me elders 

 so.

Pete and Old School suggested leaving her be ...I'm jist gonna try it as is for a while and watch for a trade on the .300 Savage..
