I should be working but, I tried the other scope. Same issue and exactly the same amount off. I did some searching on this mount mount and the 340 /325 Savage Stevens and it appears that even though Weaver recommends this mount for this rifle, it positions the scope too far to the right. I'm not a machinist or, I'd mill a slab of aluminum 1/4" thick matching the radius of the barrel and mount to go under the scope base to center the scope. It would still be low but it I would be able to center it...
I also found that B-Square used to make a mount that used the same mounting holes that didn't have the problem but it's discontinued. I found a mount that looks like a copy of the B-Square on eBay under the Sun Optics brand. I suppose the next step is to look for a review on these...
