Remington 700 - 300 AAC Rechamber
I have a Remington 700 in 300 AAC - 16" heavy threaded barrel, HS Precision stock. The caliber just isn't working well for me and I'd like to explore some options, with an eye on economy of work being done. I reload. I have a 375 H & H pistol and a 416 Rigby rifle (among other things) so am flexible on practical use of the end chambering. As in, if it's a touch odd I don't mind.
I'm leaning toward staying with 30 caliber to keep the barrel, going with something on the strong side such as a 300 WSM, 300 RSAUM or even the Ruger 300 RCM. On the other hand, I'd consider something "pleasant" like the 300 Savage or even (if it can be done) the 30 Remington.
I'm not interested in going with 223 or 308, I have plenty of rifles in those calibers Nor do I want to try and "make the AAC work". I have other (semi) rifles in AAC.
Any suggestions? I'm told the 300 WSM would be the simplest job.
Also, what to do about the bolt - open up the face, trade out?
Edit: Twist is 1 in 7". This is the rifle in question, except with an HS stock:

Maybe it's a sign of the times that even in a press release Remington misspelled "brake" .... [}:)]

You didn't mention the twist of the rifling? If you have it set up to stabilize the 240 grain suppressed bullet? Likely you might have degraded accuracy. With the lighter weight 30 caliber bullets.
When J.D. Jones designed the Whisper. It was specifically for a 240 grain suppressed bullet. Although you could fire, lighter,high velocity,.30 caliber bullets with less accuracy.
Strikes me you're going to run into the same problem. Unless you use heavier bullets. For the new cartridge you rechamber to.
EDIT #1,
As per your latest post. The barrel being "1 in 7 twist", is your basic problem, IMHO. I wouldn't even screw with it. If it isn't working for you, shooting 200 grain+ bullets, with the 300 AAC chambering. It's not likely to be accurate, with any other chambering either.
I would sell the rifle as is, rather than messing with it. 300 AAC/Whisper is a very popular cartridge nowadays. Likely it would sell quick on the auction, to some gunshop commando. Who would rework it for a suppressor and a AR mag.0 -
Barrel twist?
Short action I asume?0 -
According to Remington you have a 1:10 twist, that would be perfect for a 300WSM. I have a Savage Striker pistol that is chambered in 300WSM and it is a joy to shoot, the barrel on your rifle is actually shorter then my pistol barrel but I can say that 175-185gr bullets (SMK and Berger Hybrid) at a tick over 2900 FPS have been the best for accuracy with IMR4350. Install a good break and you'll have no issue with recoil, I use a Holland and it works so well that the gun never comes off the rest. You will need to have the bolt head opened up and then it would also be a great time to install a Sako extractor. Over all it makes for a great package, but one warning, it will be LOUD, my Striker has the nickname "The Beast" and most people at the range swear that each shot will register on the rictor scale as it literally shakes the ground with each shot, but you have some boomers so it is nothing you haven't experienced before.

I love my Krieger's, one of the absolute best in the business with the competitive wins to prove it.

The gunsmiths that I know all would much rather get a new bolt with the right size face than to open a 700 boltface. t can be done, but if you are rechambering or getting a new barrel, the new bolt would be a small expense- cheaper than the labor to open the existing bolt. 0 -
Wildcat 30-222 Rem Mag. 7.62x47mm Only change the neck diameter. 0 -
Doug, a bit more has to be considered, than just a rechamber, and bolt face modification.
Is there enough on the chamber area of the rifle, to safely do so?
You will also have to change out the magazine box, and alter the feed rails on the receiver to properly feed/function.
Of the 3 chambering's you listed, the 300 WSM, is the most popular, with the most available brass. The 300 RCM, is proprietary to Hornady as far as I know, and they would be your only source of brass.
Just some thoughts...

I think all 700 barrel shanks are the same diameter, so it would safely contain a larger cartridge.
But that cartridge would have to fit the short action. Will a .300 WSM? I know the others mentioned won't.
I would not want a 16" magnum anyhow.0 -
Thanks for the responses.
This is a short action and the 300 WSM or 300 RSAUM should safely work, Remington (used to) offer their 300 RSAUM in this set up. I assume I'll have to do some additional tweaking such as a different follower, maybe box mag insert but am hoping to not have to fiddle with feed rails, which is why I included the 300 RSAUM.
I lean toward 135 to 168 grain bullets. In the 147 to 168 range the AAC case doesn't have a whole lot of room regardless of which powder is used - H110, Blue Dot, IMR 4227 for example. Trying to stuff a 190 to 240 grainer in there, getting good neck tension - I guess it can be done, but my preference is to shoot the lighter stuff. Nothing wrong with the AAC, as I said it just isn't working for me out of a bolt gun.
Rate of twist may be the issue too. With 125 to 168 weight accuracy varies from very good to "who's shooting the Mini 14?" .....[:(]
The 7.62X47 sounds interesting if I go the "stay pleasant shooter" route. I already have a 6X47/222 RM and plenty of 222 RM brass. No need to change the bolt face, pretty sure the rails could stay as is. I poked around a bit and see this is also called the "30 X 47 Lapua" and that there's not much info on it. That doesn't particularly bother me. But, the rate of twist (1 in 7")in the existing barrel might preclude use of lighter to medium weight bullets. So, I may end up having to switch barrels anyway. If that's the case I'd just as soon go with 6X45 or the 30X47 - or something that keeps the 223 bolt face & feed system.

If you need to change barrels, go with a Douglas, can't beat them for the price. Mine are tack drivers [;)] 0 -

Doug,
That is not correct. The 30x47 Lapua, is also a wildcat, but it is made from the 6.5x47 Lapua necked up. The 6.5x47 Lapua, is an entirely different factory cartridge than the 222RM. It would need a different bolt face.

The .30x223, sometimes known as the .30 Apache, would be an easy change, but it wouldn't be a magnum and I don't know what it would offer that the .300 AAC did not already do. 0
