Paul, was the part number for your Leupold base #52318? silver base savage RH 10-16. Maybe you should take it to a Gun shop ( other than Gander)and ask whats going on, there shouldn't be that much of a problem getting the base you want for your Rifle.
Then once I got the scope on there I found out there is no leeway for eye relief adjustment, Thats one reason I like the single base,

Burris claims they have them too. I wouldn't settle for anything less than what you want. Keep looking. Good Luck
