View Full Version : "High" Area Between Mounting Screws

There is a high area on the receiver for the rear scope mounts on one of my Sav. 12's.
This area is about half way between the mounting screw holes. I have a one piece
base coming which could help the problem, but said problem does cause scope
adjustment to almost bottom out to get to bulls-eye.

Has anyone else experienced this? What did you do about it?

I have no plans to send it back because this thing shot one-hole groups @ 50 during
preliminary setup with loaded rounds not even developed for it (.22-250 VLP), using
a 2-piece base.

Would a good base bedding job help out here, or should the high spot be machined
down to where this area should be? Since it is not a heavy recoiler, I am seriously
considering bedding the one-piece scope mount. Anyone ever do this?

Thanks.

On hand, I have Score High's Pro-Bed 2000 and Devcon 110. The Devcon would
be stronger, but I wonder about the metal "grit" impeding the process in such
a case as this. It is inferior to none for stock bedding, but would it be ok for
such a finely filmed metal to metal fit?

Ken Farrell says to "it may need to be bedded in to maintain the flatness of the mount using any good epoxy. We highly recommend bedding to prevent stressing or bowing of the mount, or the receiver, and to maintain the straightness of the mount." Additional instructions, including recommended torque specs can be found on his site; www.kenfarrell.com

MichaelStrauss,

I've looked all over Farrell's site and can't find the link to the instructions or torque specs. Can you be mmore specific on the link?

Thanks,

Ended up bedding with Pro-Bed 2000, using similar techniques as would be used
when bedding a stock. The waxed screws were tightened just to "snug" and
backed off a quarter turn. PB 2000 expands for a while during the first hour of
setting, so I had to "babysit" with a toothpick and q-tip. Next day, I popped it
off and let it cure another day. It turned out pretty darned good and today
the rifle gave me a few 1/4 & 3/8" 100yd groups. This little girl should be a
real tack-driver when her ROUGH barrel is broke in.
