on a rem 700 action or action with rem bolt nose. is there a spec? a way to change the spec?
headspace bolt face to chamber shoulder. correct?
im looking for bolt face to back of case head spec's. is it possible to customize the fit of the bolt nose into the back of the barrel fit to get the case further into the chamber and then cut chamber deeper for correct head space..thats the info im looking for.
 
thanks stool. but not sure that answers the question.
If you blue print a rem 700, would you take off the nose of the bolt what ever dimension you took off the lugs,face ect. then take that amount off the barrel shoulder and screw the barrel back closer to the bolt face to keep the case in the chamber?

should it be ? you do want the base of the case fully in the chamber correct?

Im asking these question soley out of courisity. purely academic.
 
a good cleaned up surface/surfaces is all we`re looking for...... MINIMAL CLEANUP.....bolt nose and bolt lugs like you`re asking about on a rem.usually can be done in less than .003" each........now the receiver face may take abit more than that....

Years ago we found out the hard way that in order to build a ppc on a rem action we had to remove .025-.030 off the bolt nose. Doing that renderd the extractor useless so a sako extractor was installed. This process allowed the chamber to be cut .025-.030 deeper to give the semi balloon head ppc case more support'. Sometimes we coned the bolt nose and barrel. This is probably the only exception on a rem. where a sako extractor was the better way to go! Having said that, you are probably better off leaving the standard rem.breeching sysyem alone unless you are going to opt for a ppc. I doubt there is a safer system. You do not want the bolt nose touching the barrel counter bore anywhere. If the lugs show good contact,the front of the receiver is square and the threads are concentric that's about as good as it's going to get. You want about .010 clearance between the bolt O.D and the barrel counter bore I.D. At least .005 between the front of the bolt and face of the counterbore, Hope that helps.

Red lines disappeared when I pushed the "submit reply" button. I'm better with remingtons than I am computers!

She must have the new 'NSA Snooper' feature which highlights the buzzwords being sent to the federal monitoring station.....

I think he's talking about barrel to bolt clearance. just make the shank longer so that there is minimum space between the bolt body and the back of the barrel.
Remington.s are generous .002 should be a nice fit.
