littlecanoe Posted December 7, 2008 Report Share Posted December 7, 2008 I have a project in mind and was wondering if a 30-06 reamer would totally clean up a 308 chamber without having to set the barrel back. I've been looking at the specs and it looks like it might but I'm out of my comfort zone here. Thanks, lc Link to comment Share on other sites More sharing options...
Sailormilan2 Posted December 7, 2008 Report Share Posted December 7, 2008 No, it will not clean the chamber up. The 308 has less body taper than the 30-06. So, the shoulder is wider on the 308, than the body of the 30-06 at the same place. Link to comment Share on other sites More sharing options...

littlecanoe Posted December 7, 2008 Author Report Share Posted December 7, 2008 Doesn't the taper change most somewhat forward of the webbing? If a bit of setback of the barrel was required how much would be needed? Link to comment Share on other sites More sharing options...
z1r Posted December 8, 2008 Report Share Posted December 8, 2008 Doesn't the taper change most somewhat forward of the webbing? If a bit of setback of the barrel was required how much would be needed? A lot. Measure, or look at a drawing of, the shoulder of the .308. Then see where on the .30-06 case it measures the same. That will give you the answer. Link to comment Share on other sites More sharing options...

That will give you the answer. I did it and yes I had to set the shoulder back quite a bit Link to comment Share on other sites More sharing options...

Spiris Posted December 8, 2008 Report Share Posted December 8, 2008 LC, just wondering if the project barrel is a large ring Mauser or what? Spiris Link to comment Share on other sites More sharing options...
littlecanoe Posted December 9, 2008 Author Report Share Posted December 9, 2008 Spiris, I don't have the barrel but was looking at the 308's that fmsniper had used in a build. He found them on Numrich. I was wanting to build a heavy barrel 30-06 and thought that the barrel might be a good starting point. The price is right! The action is the Steyr that I had posted on last week. Large ring. Link to comment Share on other sites More sharing options...
Spiris Posted December 9, 2008 Report Share Posted December 9, 2008 The only option for that is to rechamber to '06 Ackley improved. It'll thoroughly clean up a 308 and give the old '06 a boost. con: FL die cost 308 schematic http://ammoguide.com/?catid=92 '06 AI schematic http://ammoguide.com/?catid=255 NCsmitty Link to comment Share on other sites More sharing options...

littlecanoe Posted December 10, 2008 Author Report Share Posted December 10, 2008 fm, I had been thinking of the 308 cal Norwegian barrels that you had bought from Numrich. I believe you had posted a pic of that rifle showing spec4 what you'd done. Did you have any trouble with feeding of the 308? Link to comment Share on other sites More sharing options...
