Hi,just need to pick your brains on something Ive been thinking about for a long time. Ive got a nice Remington 700 .308 heavy barrel,Im planning on having it blueprinted by a local guy that really is brilliant at his job. Im planning on a new Krieger barrel,a full action blueprint which includes new oversized recoil lug,pillar and glass bedding the stock and whatever else he does during a blueprint. Id just like to know what should I be expecting as the outcome after this job is done. Its grouping in around 3/4 inch at 100yrds at the moment with factory ammo. I dont reload so should I expect much with factory ammo.
What can I expect from blueprinting
- Thread starter gamma
- Start date
Give us details of what your local guy does to 'blueprint' the action, i.e. what is trued and how does he do it?
Keep in mind that a Stiller Predator or Borden Alpine might be cheaper when all is said and done...and the 'nothing left to chance ' blueprint that I insist on costs beyond these two new alternatives.
What's the rifle used for?
I wouldn't spend this kind of money and be at the mercy of factory ammo.

Hi there,his blueprinting operation involves using his own shop made blueprinting jig,rather like that of the GTR jig with the 4 alligning bolts front and back. He thrues the front face, the threads and the internal locking cams,he also thrues the bolt lugs and hand laps them. He replaces the recoil lug or surface grinds the existing one,in my case Im having mine replaced for an oversized one. And in my case Im also having a new barrel fitted plus a pillar and glass bed job. I see what your saying about a custom rifle being cheaper but this guy is my hunting buddy and he never charges for anything except for the parts involved. Without a doubt Im going to take care of him for this job but I know it wont work out too bad. I think Ive just about covered everything Im having done, What you think!!.

Having the action completely trued doesn't hurt anything but don't expect to see a huge change. You might not see any difference in accuracy over an un-trued action. Most of my 700's are trued and I usually have it done just because. But it's not magic.
Years ago I had 2 - .223's done by the same guy, 3 months apart. One action was trued, the other wasn't. These guns had identical chambers and fired brass would interchange. Even with very different barrels, both rifles liked the exact same load and were capable of the same 1/4' groups at the exact same velocity. Would that one action have shot better if it had been trued or was it real good to begin with? I don't know the answer to either question.
Another 700 from the gunshow, an un-bedded 22-250 sporter. Rechambered to 22-250AI it shot .4' regularly whenever zero was checked on paper. That barrel was put on a 722 action and it shot exctly the same. The 700 action was trued then rebarrelled and the builder told me that particular action was the worst, most out of true, 700 he'd ever seen. Even so, it had shot well.
I think a good barrel and a good, well-spec'd chamber are more important to accuracy. But since this isn't costing you anything, by all means do it. Just don't expect miracles.

Sounds like your smith may know what he's talking about. As to the 'blueprinting', I recommend it simply because it leaves nothing to chance.
So your gunsmith spends half a day getting your brand new barrel chambered and crowned to less than .0002' TIR. Why would you screw that barrel into an action that may run out .003' on the face? How about .006'? It doesn't make sense. Simply screwing a new tube on the gun MAY work alright, but you will always wonder???
All that said, if you remain a factory ammo shooter, you will never see the full potential of your rifles.

I pretty much agree with the last two responders. If you have a 3/4 minute rifle now then you'll probably have a 1/2 minute rifle after you have the work done. This can be improved upon a lot with reloading and shooting skill improvement. People tend to underestimate what it really takes to get a rifle shooting those 1/4 minute groups day after day. It isn't easy and it has a lot to do with the shooter!
