Ex-Sniper Restoration

I am about to embark on an ex sniper restoration. I have a bolt and an original '44 dated PU scope and accessories. I have read all the pertinent posts here and I thank you all for the contributions.

My question is whether the holes are plugged with pins and screws or just pins. I have a buddy who swears his 91/30 had only pins lightly welded into the receiver. He said he used a punch to tap them out, breaking the tack weld that held them, easily.

I am expecting otherwise. I have full machine shop so I am familiar with the removal process. I am hoping that they weren't too aggressive with their welding!~Andy

My experience on four ex-sniper reworks is that the inner two main screw holes are threaded and filled with screw shanks and welded I have never been able to remove one of these with an easy-out and do not bother to try. I drill them with a 3mm (+/-) small bit first from inside the receiver and then a 5mm bit from the outside of the receiver. I then tap the two main screw holes.
I drill out the pins last after fitting the base onto the rifle and tightening down the main screws to mark their position and the pin hole locations. The pin (outer) holes are drilled smooth and filled and welded with a pin. I use a 4.9mm drill on these. On a few I have been able to drive the pin out after drilling a bit from outside the receiver.
For final fit on the main screws I use a hammer blow impact driver to tighten the screws down so they are pretty tight. You will likely find the capture screw slots in the main screws do not align properly to allow installation of the capture screws. Filing the underside shoulder of the main screw will allow them to rotate far enough to align the capture slot to the capture screws.
This works for me but I'm sure there are other methods.
Have fun. It is a nice project to complete.

The pins and screw shanks are fairly hard but not that bad really. The weld is the hardest portion of the metal, IMHO. I use quality bits and have never broken one in 5 restorations of ex-PU sniper rifles. The tapping is the more difficult part in some instances. The weld spots are really hard and getting the tap started can be a problem.
