I have a Remington 700 long action that I’m re barreling with a “remage” style barrel (Savage style barrel and nut system with Remington 700 threads). The old barrel is off and everything is cleaned up. Bolt is disassembled. The new barrel starts to thread into the receiver normal and easy but about half way down it hits a sudden hard stop before reaching the head space gauge. The threads on the new barrel look perfect. The threads on the receiver have no visible obvious problems but also look like a product of mass production and aren’t perfect. I suspect the new barrel being precision cut to exacting tolerances is not happy with the mass produced threads on my receiver. Is there a tool I can get or rent to just chase the threads on the receiver? Or a gun smith that would do it for a reasonable price? I’m not really wanting to go to the expense of truing or blueprinting the action. I appreciate all the advice and wisdom y’all have. Thanks.
