Yes, I think so. Anthing is possible with suitable shafting, gearing and camming .
Others may not think so.
Yep. Called a trace machine. Works wonderfully. Its like a CMM for chambers.

... which, to me, means a 308 Win chamber has headspace at 1.630". Other dimensions can be at SAAMI spec. Best thing about that is new case bodies stretch minimally; head clearance is a couple thousandths but let's hope case shoulder setback from firing pin impact is minimal. Case life will be longest. And if the bolt face is properly squared up, once fired new case heads will be minimally out of square for cases not too uniform in wall thickness.I like the chambers on the tight side ........
the chambers headspaced with gold match and black hills ammo and reloads will end up in the 1.631 gauge. On the sticky side at 1.630.
Again, this unless you have a barrel nut system obviously.
Once you get closer all you do is
shaving whatever you need from the shoulder so slightly until you get the headspace you want.
This process might not work for someone who wants the gun to run any sort of ammunition
including surplus or whatever they can find. So there are trade offs depending on ones goals.
I guess one could take the largest NATO and surplus one could find and use those to headspace
but then will end up with a commercial type of chamber that might not be the best for
top accuracy with match loads. For an AR a chamber around 1.634 might be a better choice.
If the reamer has a floating pilot .0003" smaller than the barrel's bore diameter, that'll well center the finished chamber on the bore.Short Chambers are the ones you can finish yourself w/o a lathe.
Correct, they will.If the reamer has a floating pilot .0003" smaller than the barrel's groove diameter, that'll well center the finished chamber on the bore.
I agree, I just can not find a reloader. smith or manufacturer that list the length of the chamber in thousandths
Reloaders do not sell chambers so you will not find anything there.
Has anyone ever used the Clyner Pull Through reamers to finish a short chambered barrel?
