Chambering a Savage

I would like to know if there is a standard measurement for how much of the case should protrude out of the chamber end when running in the reamer. I am going to chamber a barrel for a savage target action in 30BR. I have never chambered a savage and I don't know how deep to run the reamer in. Any help will be appreciated.

I usually true the bolthead face if it needs it. Usually they do because Savage uses a vibratory deburring operation on the boltheads and depending on how long it is left in, can cause the boltface to be dished. You have to be careful here so you don't remove too much or it will lead to extraction problems. After that, I depth mic from the bolt nose to the bolt face and add .oo4-.oo6 to that measurement and make the go gauge stick out the breech that much. Any less clearance then that and you risk not being able to close the bolt if you should happen to get a piece of unburnt powder or dirt in between the bolt nose and the barrel. You could safely go up to .010 and not have a problem, but I like mine a little closer.

Are you saying that the go gauge should protrude 4 to 5 thou out of the barrel and that is the correct dept to run the chamber reamer in. I think the gauge would need to protrude more then 4 to 5 thou. I had a guy tell me that the case should stick out of the chamber between 120 and 125 thousands and then to screw the barrel on until the case contacts the bolt and tighten the barrel nut. Does this sound correct Ross
 
If you measure the depth of the bolt face recess you will find that it is about .115" or so. Add .005 to .010 and you end up with the case app .120 to .125 out of the bbl.

ETA: If it was me I would eliminate the bbl nut. This will make for much faster bbl changes.

If you re-read my post, what I said was, After I true the bolt face, I depth mic from the bolt nose to the bolt face and ADD .004-.006 to THAT measurement. So yes in the neighborhood of .125 but you have to check your individual boltface depth to see what it actually is. BTW is this your first chambering job?
 
Hi
This is not my first chambering job. I have chambered several dozen Remingtons but never a savage with a barrel nut. I may do away with the nut and use a larger barrel and chamber it like a remington. I am not sure I like the barrel nut because it limits the diameter of your barrel unless you make larger barrel nuts. Thank you for your help Ross
 
I treat them like a Rem. and short chamber, then finish up after I install the barrel.
 
I think the barrel nut is a great way to achieve fast barrel changes and great head spacing precisely. You can get custom nuts from Holland's still I think, also a custom recoil lug would be in order too over the factory one. Good shooting.
