Action blueprinting??

Just a question. I see parts on midway and brownells for blueprinting remington actions. Can you blueprint a rem 700 action without a lathe or do you need a lathe for all these parts? Thanks

Yes. There are hand tools that you can use to "blueprint" your 700 action.

You can also blueprint a spaceship with a Big Chief tablet and a No. 2 pencil.

How good do you want it to be?

Re: Action blueprinting??

I did not pull up the tools listed, but have a short answer for you. Yes you can to a great degree true up the action body, BUT you cannot true the bolt lugs without a lathe. I still think that the bushing system can give some benefit by trueing the action face and lug abutments and to some degree the action threads, especially if you also get one of those boltface truers. If you were to cut the action face and and lug abutments, lap the bolt into decent contact, and then use the bolt face truer you are going to be about as close as you can get without a lathe. Another thought would be to buy the oversized PTG bolt and use the action reaming tool.

With the amount of play in a remington, and the cocking piece induced cant, and the way they seem to shoot anyway, leads me to thinking that these actions are not as much of the total accuracy package as some believe. I have been told by an old BR shooter that so long as the barrel is good, the chamber is semi straight and the bedding is good, they will shoot. Don Geraci builds about the best shooting rifles I have ever seen, and he will only true the action face and lap the lugs. He thinks everything else is just fluff. With his track record of routinely sending 1/4 MOA remington based hunting rifles out the door I have to think he is right.

I use the fixtures at times, sometimes I true them in the lathe depending on how I feel. I have not noticed any difference in accuracy. Still if it is a confidence issue, which I feel most of what we do to these actions is, you are probably better off sending your actions to the smith. If I recall I spent about 700+ tooling up to true actions.

Thanks... Very Informative. I have an older rem 700adl 243 that I am going to re-barrel myself with one of the rem-age barrels which allows one to re-barrel a remington action with a barrel nut system like the savages have. I thought it might be beneficial to try to true the action up a little first but want to do it myself. I am not to cheap to pay someone. I just like to tinker with things and think I would enjoy it. I don't have access to a lathe so I have been looking at the PTG stuff but wanted some input from others who may have some experience with these tools. Also I have seen videos with guys using compound to true the bolt lugs up and just opening and closing the bolt. Does this work?

Lapping the lugs is good.

But they need to be pretty true already, or you could be at it a long while.

Re: Action blueprinting??

Does lapping help? I dunno what the real effect is. It is easy and quick, so I do it usually. That is one of the things that someone could actually test the benefit of, but have never thought to test it. I guess the method would be to build a rifle without lapping, then shoot it. Then lap them adjust headspace if needed, then shoot it again to see. Someone ought to give that a test for the rest of us dummies to see if it really helps. Something else that would be interesting would be to then test the boltface truing tools. I like doing tests and am usually testing something....documentation of testing is another thing...I am not really prone to that.
