What is meant by blueprinting and what are the benefits.

"blue printing", is in a nutshell, taking a mass produced factory action and re machining it to the dimensions it should have been when when it left the factory, according to the blue print.

The benefit is that all parts are square and true to one and other ie. action, barrel etc. It insures consistency and intern that consistency equates to increased accuracy.

WOW oh WOW - I had no idea that in an industry like this, that QC could go so far wrong.

Thanks for the insight.

Its not that they are so bad, just that they don't try to achieve perfection and have to keep the
cost down to be competitive. lots of People want cheep prices and for this they get poor quality
and minimum Quality Control.

Most good Gun Smiths want everything to be as near perfect as possible because they are held to
an accuracy standard and by doing rifles one at a time can reach there requirements.

I have blueprinted lots of factory actions that needed very little truing, but some needed everything
trued, so I true/Blue print every action I build on as part of the process.

Life is too short to have inaccurate guns.

A-MEN to that !!!!!

That is why all parts including the action have to be checked and assembled in a craftsman ship
like manner .

If you eliminate every possible issue the rifle will be accurate if you feed it good ammo and have the skills to shoot well.

Assume nothing and check everything, No matter who makes it.

Not many realize how small .001 is in reality. The average human hair is .004 so that should put it in perspective for you. To achieve the accuracy he is portraying in those videos a remington 700 would cost what a custom gun does from the factory. Typical tolerancing on most machining operations are +\- .005. So even from the factory it may be within their standard of tolerancing. But isnt perfect. Indicating to .0001 is extremely tight. I enjoyed the videos and it really showed me a lot. I am a cnc machinist and have respect for the fella in the video. Not many know how hard it is to work within a .001.
