I have a savage 23d that belonged to my father, he got it in a trade. I used to shoot it back 35 years ago. It is not a collector, barrel had been cut off, two of the holes for the side mount scope base has been filled. It has an old savage 4x japan made scope on it model 0415 4x15. I want to upgrade the scope and try and work up a load for it. Never could get it to shoot back then. My problem is the top two scope mounts are to far apart to mount a modern scope. Does anyone know of a base I could get that might work with the existing top mount holes? I found an old post where someone used a scope base blank from Browells. They sell two that are curved on the bottom but don't know which one will work. I would have to get someone to drill the holes if I went that route. Thank's for any help.
