Gunsmithing AIAW Barrel

[onetoe]

I would appreciate some help. I would like to know why and if it is necessary, to have the chamfer on the chamber bore and why the threads are cut back on the OD of the barrel where it goes into the receiver on the bolt side. All my AI barrels are machined this way. I have one that was done by a gunsmith that is not, thanks in advance.

Great pics. I would think, not know, that the chamfer would maybe help with feeding and reduce bullet tip damage going into the chamber?? Just a guess.

The Chamf. will indeed assist feeding & the thread is short from the end of the barrel as this is to clear the thead runount in the action infront of the lockring.

Re: AIAW Barrel

agreed... this is a common practice... only the first few threads from the shoulder do any holding anyway...
