Hey guys I am building my first custom rifle in long action would you give a list of procedures to have done for absolute top accuracy, I want to make sure I get it right the first time and not have no regrets also should I have bolt sleeved.
 
LG,
To do it correctly it will cost more than a custom. If you really want it right, sell your factory receiver and buy a custom. I spent close to $900 on my Grandson's Remington 600 last year including $200 for the receiver. This was just on the receiver and Modifications to it. It was as good as a custom that you can buy for $700-$900. I believe Mike Bryant's website has better info than the link posted above.

Hey, Butch what procedures did you have done specifically. I have to much money invested already have to make this action work.
 
I bought the receiver and sent it to Mike Bryant. He reamed the raceways, recut the lug abuttments, the face of the receiver, and recut the threads. It was done in a lathe. Go to Mike's website and you can see how a proper job is done. I ordered a new bolt from Pacific Tool to fit the raceways. I bought the one with the small firing pin hole, a 3 POS safety, and a firing pin assembly to match. I also had the bolt fluted. I also bought the one with the Sako extractor and installed it. I sent the bolt to Dan Armstrong in Fairbanks, Alaska to weld on the bolt handle. He is the best. I sent the receiver to Karl Feldkamp to have him make his G33/40 cut on it.

It became a 6X47Lapua and is a very accurate hunting rifle for him using Bib 95grn. bullets. He is 9 yrs. old.

Butch,
He is fortunate to have such a nice Grandfather.
I get the impression you might take a different route if you had it to do again though.

Dick,
When you think you know it all it comes back to kick you in the A$$. I figured that getting parts with a discount and having my buddies help me it would be best. Even with all the help I got, I should have bought a custom receiver. The value of the rifle would be more with a custom receiver, but I doubt that Pearce will ever get rid of it.

Have you shot the rifle first to see if it needs the action "accurized"? It may not. Last wednesday I shot a 200-14X, 600 yard, 20 round relay with a .260 chambered Bartlein barrel and stock (untouched) Rem 700 action. I personally believe (others may not), that factory new 700 actions being built using modern CNC equipment are as accurate in dimensions as any gunsmith can reproduce. I am sure there are exceptions to this.
 
model14,
That is a little hard to do when you start with just a bare receiver without a bolt. One of these days you may be fortunate to have a Grandchild and then you would better understand. I could have bought him a Mod 7 youth model and it would kill them just as dead. That ain't the point.
Glad you got one of the few good Remingtons. I believe that the Bartlein saved it as they are producing some real trash when it comes to their barrels. Not like they used to be.

What kind of "custom" rifle are you thinking of to build? Caliber? More details are required?

Nice action Butch but I would much prefer the original 700 extractor. All the precision in it still leaves the raceway wide open behind the extractor conversion...

I have seen new and old 700 actions both good and bad in tolerances... I think all you can say for sure is mass produced factory actions vary in tolerances... if you get a good one, not as much needs to be done. If you get a bad one more is required. All of them, even the worst with no work done on it will still shoot 3/4 moa or better in hunting configuration with a good barrel installed and a good bedding job.

700 accurize

Thanks a lot Butch that is what I was looking for, The way this project got started was I bought a 300 ultra mag. model cdl. In the box,That was all over paper at 100 yards no matter the bullet or powder weight. I sent it back to the factory and they recrowned the muzzle and lapped the chamber,they shot it at 100 yards with two loads one was a 1.250 the other 1.50 inches they said that was factory specs and sent it back. but that's not good enough for me,so I have become obsessed with making this gun shoot accurate.I have a hart Br.1000 barrel and McMillan stock on the way, I am just trying to to get my ducks in a row with this action.I've spent this much already I don't wanna cut any corners now.I appreciate all your guys help.

What you oughta do is sell the clunker as is. Then buy a good custom action (like the Stiller or Pierce or whatever) and use IT as the basis of your new rifle with the barrel and stock you've ordered.

You can drop a new engine and brakes and race seats and new wheels and transmission in an old clunker, and spend more than you would on a BMW M3. But it will NEVER be what the other is.

Unless you have an emotional stake, or "obsession" in such doings, the smart money is to get the good stuff from the start.
 
Okay here's what I have a Remington 700 left hand action and a stock on the way to fit it. Is there any custom actions out there that would fit in this stock like my action is going to.
 
I know Pierce offers a left handed action and should fit the Remington footprint. They will no doubt out do a Remington action and the price is right.

On a 700 you want to do the work Butch posted above and then you would normaly double sleeve the bolts body and sleeve the firing pin to 0.062 and pin the recoil lug.
I had Mike Bryant do one for me and it really shoots quite well.
If I was to do it again I would order a new bolt from Pacific Precision because you get everything you want and you get it much cheaper.
I would order a 0.704 bolt diamter.I would get a coned bolt face.I would get a 0.062 firing pin hole and the firing pin assembly at the same time.
If you send it to Greg Tannel or Mike Bryant they are used to this type of work and it will come out right.
On the bolt handle make sure to send the receiver with the bolt even if they don't want it.

It's the tolerance stack-ups, poor workmanship, and poor QC standards that make this statement doubtful. Granted some very few factory rifles may be as accurate as a custom, but I would bet they got the luck of the draw with exceptional tubes rather than close toleranced matching components.
Why not take yours apart and index it and let us know how true it is?
Also aren't factory receivers heat treated AFTER machining adding a distortion component to the equation?

Find a Smith that is not giving you a package. One the will start at the reciever face and move back. Once it is true that is it. Sometimes with packages you pay for stuff not neededing done. Start with a Kelby's, Stiller, Lawton, Borden, Defiance. They all are good Find a good smith to hang a good barrel on it. Once you are bored they will bring two to three times as much in resale.
