Filling in Receiver Holes

I have a PH 270 that I need to fill and redrill one of the scope mount screw holes on the rear part of the receiver. The problem is that I need only move the hole about 1/2 of the hole size. Will filling with Devcon and then redrilling and tapping the new hole work? Keeping in mind that the Devcon will be part of the new hole? Or would I be better off, annealing and peening a screw into the existing hole and then attempting to re-drill and tap. Also, would I be able to use forming taps rather than cutting taps to create the new threads?

Devcon would be bubba's method.

I would have that hole either TIG or MIG welded by an experienced welder.

Or I would silver solder a screw in that hole and then dress it off, drill and tap.
 
Silver solder I have access too and I know a few TIG experienced welders. I'm a little leary of using MIG to fill a hole that small, I think the wire would be moving far too to fast at the amperage needed to get a good, clean weld.
 
Might be easier and less expensive to move the hole on the scope rail....scope rails are cheaper then receivers. Have someone weld the hole closed on the rail and make a paper template of the hole in the receiver and redrill the rail. That way if you screw up the rail, It cost you a couple of dollars..not a new or rewelded receiver.

That's good advice right there quinnbrian. A mistake there would be much less costly.

My one and only attempt at that, for "half a hole", the drill bit followed the Devcon back into the old hole. Maybe a correctly sized centre bit would do it, but basic twist drill flexed too much. Parent metal was much harder than the Devcon... And, bonus, it was not on a firearm at all!!
 
i would hog out the hole on the bas. fill with devcon and re drill in correct location. cheaper and easier the messing up the rifle. if your worried about the base moving latter a drop or two of loctite under the base would work.
