Hello,
I have a Savage 99 that I purchased used, with the scope mount holes not properly lined up. Can the holes be filled in and new holes drilled & tapped.
Thanks.
 
I've seen mis-drilled holes filed with a bolt, cut flush, peened over, filed smooth and re-blued. They still show and its kind of Bubba.

If you have a good mig or tig welder you can put a screw in the misaligned hole and do a very short spot weld to fill it. The receiver would have to be kept cold and the weld duration would have to be very short to minimize the volume of metal that gets heated. The weld is then draw filed and new holes are drilled and tapped. On the Savage 99 I would remove the barrel before doing this to the front holes and would get a welder with some skill and knowledge of heat treating to do the rear holes. Too much heat and you will have a receiver that will shoot loose very quickly.
I am aware of at least on gunsmith willing to use this method to fill hole on the bridge of M98 but not the front holes near the locking lugs. Probably not a prudent decission to apply welding heat to an area that needs to support high pressures.

The bottom line, take it to a gunsmith or machinist that has the tools and skills and let him decide.
 
The problem with misaligned holes on Savages is fairly common (sometimes the problem is that the barrel is not mounted square to the receiver). In any event if the problem is the screw holes off to one side (usually the right) simply use wind age adjustable rings or bases and this will solve any scope alignment problems. This will only work if all four holes line up straight but angle to one side or the other from the centerline of the barrel. Phil.
 
Savage 99

They are off to the right side....but the back is actually twisted, meaning the rear base isn't flush to the receiver. I thought about the Burris inserts, Devcon etc. Would definately send it off to a smith, but just wasn't sure about the front area of the receiver and any type of heat or current affecting the steel strength.

Thanks for all the comments, it definately helps hearing from others on here.
 
Depending on how badly aligned .. the holes can be re drilled larger .. and true to the bore axis this time ... and helicoil inserts used to reduce back to 6-48, 6-40, 8-40

a machinist can do this... I guy with a Black & Decker hand drill cannot!
 
If not too far off the holes can be re-drilled and tapped to 8-40. If they are too far off they can be plugged and redrilled in such a way that the repair is nearly invisible; comments above notwithstanding. I'm sure there are gunsmiths in the Winnipeg area capable of doing this correctly. Regards, Bill.
 
I would go with some Burris rings with inserts first. I have mounted scopes 'straight' on some receivers where the front and rear ring were visibly #### eyed.

The inserts took up the problem and the scope was held true.

Way easier then mucking with smithing.

If this is not an heirloom, you might look at putting new holes in a different spot leaving the bad ones alone. Just drill new holes in a one piece base and have at it. The bad ones will be covered by the base anyways.

X2 with what mysticplayer says. It would be easier to modify your bases or even get custom bases built than to #### around with filling and heat treating the receiver.

Just have to drill out the threads and if possible ream a new hole. press in a piece and file it\polish it to suit, than re drill and tap and then re blue.
