Pre-Chambered Barrels

What steps need to be completed to install a “pre-chambered” barrel onto a Rem 700 action? Does the “pre-chambered” configuration save a smith time compared to shortening/rechambering an existing overbore (.243) barrel with extensive throat erosion?

If accuracy is your goal , let the smith do it all . Chances are the pre chambered barrels chamber will not be exactly what your smith has to finish ream . I've seen many with 2 dia necks .
 
a prechambered barrel will take more time and not as good as a barrel done from the start by your gunsmith and one reamer. you may even get a "surcharge" for the extra work involved.
 
What exactly do you mean by prechambered?
If you mean Remage style these barrels use a barrel nut that you would need to buy also. These would save alot of time. Only takes minutes to swap them.

before the savage nut craze there was barrels that had threads and counterbores in them and a short chamber.
 
Just get yourself a Remage barrel with a nut. I hope to the Craddock Precision barrels for sale here soon. They are simply outstanding. The first run will probably be all Rock Creeks barrels.

I know that a lot of guys consider anything under 1 moa to be acceptable accuracy. If that's all a guy wants then go for one of these pre-chambered barrels. Just pick one. For the record there are many videos online of these companies holding the barrel in a collet, in a cnc lathe, doing the machine work. No competent gunsmith would do that because most barrels are at least .005 out of true on the shank, chambered one yesterday made by a high end barrel company that was .009. Those are the facts.

It begs the question, why would anyone that wanted a rifle that shot well want one?

If it shot well it would be an accident.

The other thing a guy has to wonder about is why do guys extol the virtues of barrel manufacturers that are never on the equipment lists at major competitions, unless of course they're selling the stuff.
 
Some people machine better than others... I know that for a FACT. And to put "all" manufacturers in the same boat would be like putting "all" gunsmiths in the same boat. My Craddock prototype barrel is a Criterion blank, which I don't even consider that great of a blank and it already shoots 1/4" during load workup. Can't wait to get my Bartlein 5R from Craddock.

And to say a Remage barrel shooting well is simply an "accident"... Well... I will just refrain from commenting on that ridiculous statement.

As far as being on equipment lists, I keep hearing that over and over as some kind of proof of anything concerning equipment. It is a red herring. For every guy that won, there were a whole bunches of guys that got their ass WHOOPED with their equipment...

Time will tell.
 
It is not an accident for a pre-fit to shoot well. I have a Criterion on my Savage that shoots very well. If you search a bit you will find there are several national records held by shooters using Criterion barrels.
 
Many, perhaps most National level events will post an equipment list of the top 20 or 25 finishers at an event. I suppose Criterion probably makes some very good barrels, they will be recognized as such when shooters that are consistently at the top, pay their hard earned money for them.
It may be hard to understand and appreciate but I know several hundred shooters that use for the most part BAT actions on their match rifles. These actions consistently headspace within a few thou. of each other, so you could go to a short range br match and unscrew the barrel off of competitor A's rifle and screw it on competitor Z's rifle and it would very likely headspace correctly. But none of these guys uses a prechambered barrel from one of any of the outfits that sell them. As a matter of fact I know several guys that have won blanks at matches made by a wide variety of barrel manufacturers that are not Krieger, Bartlein, Lederer, Obermeyer etc but are some of these second tier companies. Some of them were actually chambered and installed on a match rifle then were promptly stood in the junk barrel corner or were given away.

If these guys want to be recognized as having good stuff, they need to get guys like Wayne Campbell and Eric Cortina to use them and win with them. Three guys that won something isn't a very large sample.

Yah, I saw so and so bragging on Youtube that he gets a lot of that whizbang stuff for free or significantly discounted.

Then he proceeds to tell people that if they don't have this or that, don't even bother trying to compete.

I really don't care for it. Although I know I am in a minority of people that seem to worship those people.

No offense, but who cares? Short line BR is probably one of the smallest factions of rifle shooting competition in the country... You are talking a small percentage of a small percentage... Literally 1 in 500 competitive shooters in the USA are short line BR shooters.

And this thread isn't about BAT actions and short line shooters. It is about pre chambered barrels, which are being used in competitions all over the country as we speak.

Short range BR is only used for an example, the same could be used for F class, PRS, and some others so why, if it's so good, don't more of those guys use them?
 
It's a ridiculous straw man argument. We were talking about prefit barrels, REMAGE barrels and you are talking about BATs being used in competition.... Not a lot of REMAGE prefits and prechambered barrels there... Hmmm. No I guess not.

You seem to be confused.
 
One of the main reasons you haven't Been seeing more REMAGE barrels is because none of the REMAGE barrel manufacturers have been using premium barrel blanks. I was hoping to get Paul Craddock (who is a GUNSMITH BTW) to do a run of the 6BRA with Alex Wheeler's reamer using the new Rock Creek 4 land barrel (still need to secure a reamer). I am hoping for a run of ten in 1-8 twist this year. I suspect they will all be gone in a day.
 
One difference in the savage and remage systems is the floating bolt head. On a savage you can chuck it up in a 3jaw or collet and get acceptable accuracy- not so with a remington. That was a part that was lost in translation when people got excited about mass producing remington nut barrels. Like the guy above with the .009 runout. Add in 3 jaw runout and other tolerances stacked in and you may not even get the bolt nose in there. I wish em luck and maybe someday we’ll see em in the match results in a more competitive match.
 
If you want a Remington that has the good features of savage and then some , get a Remington 783 . Takes savage barrel nuts , plus a lot more
