Trued vs untrued action Data Only please

[okie]

I have a nephew that could do it....every time he comes to my house breakers pop and blue sparks fly, something catches on fire, there might be a water leak and some small animal dies.

LOL sounds like my 7 yo---mischievous is an understatement

Would someone please tell me what the heck this is? The only timing I know of on a Remington is how you attach the bolty handle to the bolt body. What "adjustment" of "timing" is a on a Remington style action?

Put simply, it's ensuring that the bolt cocking piece hits the sear at exactly the right moment so that you aren't forcing the bolt closed against spring pressure, creating a "cock on close" feel. If you have access to one, run the bolt on a Borden action and compare how it feels with a stock Remington. It's night and day.

If I were to do a test I would not test an action and then true it, I would simply have a about five of each. I know in practical terms this sounds impossible, but in industry there would be even larger groups. The larger the sample the better the results. But testing could certainly be done, and a study of the data could show trends without a doubt.

The trouble is that there is no economic incentive to do this test. A custom action that is simply made to higher standards doesn't cost a whole lot more than a trued Remington (even if you ignore other valuable custom features). When amortized over many thousand rounds, the difference is basically nothing. That puts a ceiling on the price tag for truing work and it's not much. Outfits like LRI have turned it into a semi-production process, further lowering the price tag. You would need to have a whole lot of truing work lined up to care enough to spend the cash on a test like that. It would not surprise me if truing actions falls out of practice all together in the future. There are just too many good reasonably priced customs out there to mess around with a Remington these days.

It seem to me that if you only had to take the threads .005 deeper to clean up. You could still use the same barrel without rechambering?
The threads would be a little sloppy but they should still be safe,maybe even center up better then use same size recoil lug ground true for head space. Or adjust recoil lug for any other change in headspace.

I think precision shooting magazine did a interview with mike walker about his testing on this subject while developing the 40x action. If I remember right about the only thing he found that improved accuracy consistently was grinding the od of a 700 action.

I was given the twin barrel to one of my Savage benchrest rifles. The maker said he accidently turned the threads slightly undersized and could not sell it.

Shots EXACTLY the same.

Damon, why compare a trued rem to custom? The point is comparing an untrued action. Back to the original question, is there data to support the importance of truing?

Well said, today, on top of trueing costs, need to add bolt timing and firing pin hole bushed on new actions. Now you're at 400+, easy.
Today I consider a "test" an advertisement, either someone is proving his opinion right, or gains(financial) are to be made.
