pcon Posted February 11, 2012 Report Share Posted February 11, 2012 Hi guys, Just wondering if a button rifled 32" .308 barrel was used for a couple thousand shots and then was cut back to 30" and re-chambered what are the likely effects on 1. accuracy and 2. barrel life ?? thanks pcon Link to comment Share on other sites More sharing options...
1967spud Posted February 11, 2012 Report Share Posted February 11, 2012 people do do it but with mixed results take your barrel to a reputable riflesmith (there are several on this forum) and let them have a look down it with a borescope for a verdict Link to comment Share on other sites More sharing options...
The Gun Pimp Posted February 11, 2012 Report Share Posted February 11, 2012 pcon, You will lose about 50-60fps muzzle velocity but accuracy shouldn't be affected - though you may need to 'tune' your load of course. Barrel life? Should almost be back to 'good as new'. Cheers Vince Link to comment Share on other sites More sharing options...
Ronin Posted February 18, 2012 Report Share Posted February 18, 2012 Just done this with my 6.5x47, took two inches off the barrel after its had circa 2.5k rounds through the LW barrel. Loaded ten rounds of my original load today (39g Varget, CCI BR primer, 123 Scenar) Coudnt believe my eyes when I saw that the first five shot group measured .250", velocity 2980 fps......

Offroad Gary Posted February 19, 2012 Report Share Posted February 19, 2012 A stubby 23". It was 26 andy, is that measured to bolt face or front of action? Link to comment Share on other sites More sharing options...
Ronin Posted February 19, 2012 Report Share Posted February 19, 2012 Front of action Gary. So offically the barrel is 24" total length. Two inches removed from total length, also recrowned and removed a ferom the muzzle end, extended the M18x1 mm thread to bring it back to length. Well pleased with the alterations. Rifle ready for CZ comp now, maybe some stalking too... Link to comment Share on other sites More sharing options...
