12FV Scope Mounting Holes to Big?

[kingair350]

Hi,

I purchased a new Savage 12FV in .223 from Cabela's today and when I tried to mount the Weaver 2 piece scope bases (#46 as suggested on Savage's website), the included screws just spin around and don't make any contact with the threads. The screws do this in all four holes, with or without the bases set in place. I then tried a set of Burris Xtreme Tactical Steel (2 piece) with same result. Anyone heard of this before? Seems like a defect from the factory. Not sure if I should try and take it back to Cabela's or go directly to Savage.

Thanks,

Matt

Sounds like the holes are a #8 screw instead of the usual #6.

It sucks getting old...it seems I remember someone saying that they had ran into this as well, but I cant remember where it was.

Not sure how it is in your area, but around here, one can return rings and bases and its possible someone returned the wrong ones.

I've bought a complete set (all of the calibers) from them, I had to chase the threads in 2 of the guns but they were all the same size. Thinking about buying some more in 6.5 and 308 to covert to other calibers.

I measured the size of the holes in the receiver with a caliper and comes out around .167" Does that sound like a #8 size screw? The screws for the bases I already have are .137" So far, I haven't been able to find anyone selling two piece bases that use 8-40 screws. I'd rather not go with a one piece base but I may have no choice.

I just went thru this with my desert tactical. I wanted to use my DNZ 1 piece scope mount from my Savage muzzleloader. I pulled it off and went to put it on the new desert tactical. Lo and behold it seems they drilled for the larger screw pattern. 8-40. DNZ wanted $40 to drill the mount for different size screws so I went with vortex low rings.......after a long wait it all turned out good.

Here is a machine screw tap drill chart. Check with EGW for a 1 piece base as they usually offer #8 screw option for a very small upcharge.
