Savage blueprint question..have cake and eat it too ?

One of the advantages of a Savage, for varmint work, is the availability of pre-chambered barrels...but if one does a classic blueprint that includes single pointing the threads, this goes away.....or does it? What if a small shank action was recut (in the process of being blueprinted) to standard large thread diameter thread diameter? Wouldn't you be having your cake, and eating it too. Comments? Thoughts?
 
PT&G sells oversize bolt bodies for Savages. If you true it like a Rem700 you will need a tight fitting bolt body just like the Rem700 does to benefit from that ype of truing job.
Or make a modification to tighten up the bolt fit.

What is the advantage of the oversize bolt body, or boring the bolt on a Savage with it's pivoting bolt head? The benefit of a close fitting bolt on Remingtons is to eliminate bolt head flop that is in some sense unavoidable because the Remington does "not" have a pivoting bolt head. On a Savage I can see truing the receiver face and chasing the threads if they are not aligned with the bolt bore or are eccentric to the bolt bore (I've seen all combinations), but no benefit to reaming the bolt bore and fitting an oversize bolt, especially if the oversize bolt doesn't have a pivoting head.

I believe that the what is being sold are bolt bodies that accept all of the other parts form the stock assembly, including the head.
 
When the sear is released, the bolt body rattles inside the raceway. Any rattle before the bullet leaves the bore WILL cause a POA shift.
IMO, truing a 700 without tightening the bolt fit is pointless.

I hadn't thought about it, but in theory, you should have your cake and eat it too. As long as removing 0.065" from the ID of the receiver doesn't create a strength/safety issue, it should work just fine. That said, I don't know if removing 0.065" (thinning the wall by ~0.032") of material from the ID of the receiver has a significant impact on strength or not.

I have two small shank Savages (Model 10 and Model 112) and one large shank Savage (Model 12 LRPV). The LRPV has a more substantial receiver than the 10 or 112.

FWIW: None of the three has a bolt rattle issue anywhere even close to what my one and only Rem. 700 has.

frwillia,
Could you measure the front receiver ring diameters of your large and small shank actions, and get back to me? It would seem that your findings will be a determining factor in determining the feasibility of what I have proposed.

Yup. Front receiver ring diameters:

Model 10, small shank, 1.357"
Model 112, small shank, 1.356"
Model 12, LRPV, large shank, 1.351"

So my large shank Savage is actually ~0.005" smaller than the small shank receivers. Who'd a thunk it?

I'm no expert but I'd say you're idea makes a lot of sense. Next time I have to chase threads on a savage action I'll take it out to large shank size.

Thanks

you set that whole thing up just so's you could reply in a palindrome..... you speak Klingon too?

Action Truing

Boyd,

You could blue print first with the instruction to the smith that if he has to do more than just kiss the threads he is to open to the large size. On the last two Savage actions that I trued the threads were running so true with bolt bore I didn't have to touch.

Boyd, I have done exactly what you are proposing on two LA small shank savages. The customer sent me one, that he wanted for using prefits in the RUM chamberings, and felt better with a large shank. The first one made him so happy he recently had me do a second. I single point the reciever face, threads, lug abutments and bolt face.
