[QUOTE="James Jones, post: 185796, member: 8843"] I bought a Rem 700 LA , barreld action from a local guy for a great deal , the barrel is shot out and he stated that (3000+ round 6mm Ackley) but the gun was supposedly built by a highly reputable builder , fully blue printed rear of the bolt hase been sleeved the works , I pulled it appart and looked it over checked everything and it all mics out great , threads are cut .015" over spec. I measured the barrel shank and recodered everything so I would have record when I rebarrel. Well last night I decided to rebarrel it with an old SS douglas #4 barrel I had , checked everthing again dialed in the barrel and started cutting , I always fit check my threads so they are nice and tight. I tried to thread the action onto the barrel and woulden't get a full turn , so I made another .002" cut , still woulden't turn on. I stopped knowing I was at the same measurement as the old barrel and miced both and the new barrel was .001" smaller , *** !! So I take a closer look atthe threads on the old barrel and see that they are not strait , the look almost like a buttress thread but backwards , obvously when the barrel was threaded the guy diden't have this tool square to the part , not a probelm as long as your cut the action and barel at the same setting but now I have this action whose threads are dicked up and crooked and I don't see how I can straiten them out without seriously messing up the thread pitch or cutting the action VERY thin. I have heard of some guys cutting their threads half with the compound and half with the cross slide or adjusting their compound at 32 deg rather than 29.5 and claiming that the use a "special thread pattern" so that they would get tha repeat business for the rebarrel and when the next poor bastard has to deal with it their screwed . I'm not sure what I can do to fix this , I'm still a bit upset and haven't realy thought the trouble out clearly , so I fugured I'd ask you guys your oppinion. [/QUOTE]
