I have a model 7 .223 that I am thinking about re-barreling and one caliber I am considering is 257 roberts. Will this work?

Bolt face not the same, .223=.378, .257=.473.

so I'd proly have to go .243 or .308...and if I go .308 I'd have to have my little girl shoot reduced recoil loads.
Thanks for the info.

Head diameter of the .243 and the .308 is also .473.

Condider a 6x45 or 6x47. Low recoil and accurate. Otherwise trade into a model seven with a .473 bolt face.

I have a 257 Robts built on a 700 S/A BDL action. Sweet shooting, tack driving rifle. If I were to do it again I'd give serious consideration to using a L/A and adding a magazine block, so that the heavier bullets (117s) could be seated out further, but feeding would remain reliable. 100gr or less, the S/A is fine.
Right now I'm contemplating a 6.5 to take the Roberts place - .260, 6.5 x 284, or possibly a 6.5 WSM.
I never thought I'd grow up to be a grumpy old man, but I did, and I'm killin' it.

I would not want a .257 or a 7x57 on a short action..I want both on a 30-06 length action..

Ray and I disagree about this, at least about the .257. The 7x57 needs at least a 3.1" magazine, but the .257 was designed as a 2.8" overall-length cartridge from the get-go, and works fine in a short action. I have owned a bunch of them, and 2 right now, and the supposed "advantage" of a long action with 115-120 grain bullets amounts to about a 2% (theoretical) increase in muzzle velocity, or about 50 fps with heavier bullets, which means zip in the field. In reality thye variations between different barrels will be that much.
I have always been able to get 2900+ with 115-120 grain bullets even from the short actions. The published +P data will do it these days. If extra velocity means that much to you, why not just get a .25-06 or .257 Weatherby? Those will get a LOT more velocity out of a long action than seating the bullet out on a .257.
The other factor is that standard .257 reamers (and all factory ammo) are set up with a throat for 2.8" ammo. You can get the throat lengthened, but why? Get a .25-06 and an extra 150-200 fps without leaning on the poor little Bob.

I have built 257 Roberts on Rem 700 SA's and Standard Mausers (Obendorf). In my opinion, both work fine. I tend to stay with 100 Partions or 110 accubonds on the heavy end. I would build a Roberts on whatever you want.
My only question would be if the box length on a Model 7 and a Model 700 are the same? I'm not sure?

257 Roberts same as a 6mm Rem in length, both work better with a long action.
The reason is simple, as the rifle is fired the leade grows. You need to be able to keep seating the bullet out further and further to "chase" the lands to maintain the "sweet spot" in seating depth.
I have had numerous 700's in 6 Rem and they ended up being single shots.
For a guy that shoots 30 rounds a year on deer, extreme accuracy may not be an issue.
Be darn sure to take heed, look before you leap. The very best 6 mm Rem I owned was on a long action...257 Roberts is the same parent case, which is the 7x57.

One was a short action, the other two were on long actions. All functioned smoothly. I personally wouldn't agonize about action length. My inclination is to focus more on the quality of the action, barrel, and 'smithing work that puts it all together if either length is suitable for the cartridge. Mule Deer is spot-on about performance of the cartridge.

The others have pretty much said it. I'll vote "it doesn't matter" on long or short, at least not really in favor of a short if you are going with a x57 case. I have an M77 25-06 that I'm going to set back and rechamber in Better Bob, the long action or short action is not a deal breaker with me. If I have a long action and a hankering, the couple ounces really don't matter, nor does the couple tenths in potential accuracy from the "stiffer" action.

I love these threads! (Please note I have absolutely ZERO experience with a SA 257Roberts)  Short action ... ![[Linked Image]](http://img.photobucket.com/albums/v469/2439candace/257002.jpg) Long action ... ![[Linked Image]](http://img.photobucket.com/albums/v469/2439candace/257005.jpg)

But if I have a long action and want to shoot those bullets I'll do it with a 25-06.

I mostly shoot 100gr Hornadys in mine, but have used the longer ABs with good results. I don't need the extra velocity of a bigger case. .

I'm just stirring the pot. I think the Roberts is cool at either length. And to be truthful I have an old long action 700 that may become a 257 just because I like the cartridge and I want to experiment with a short barrel.

As to the original OP question revolving around a 223 bolt face, what would be the best little gun there?
I've heard great things about the 6x47 but have no personal experience.

SuperCub, well, it just depends on which "short action" you are talking about! I just now roughly measured the mag box in a 7mmWSM Model 70 Classic (short action) and came up with about 3.03". I also have a Model 70 Classic .243 Win, which I bought some years ago, just in case I got bored and wanted to build a Roberts, and came up with around 2.85". The .243 however, has a mag block, which can be removed, which looks like it would then give about a 3.05" magazine, roughly.
Having said all that, I feel a Roberts is just fine in even a 700 short-action. We have a 700 Mountain Rifle (short-action) in a Roberts, which I got for one of my sons probably 15 years ago, or longer, which is a sweet rifle. Mucho better than the 700 Classics (long-action) in the Roberts, which we also have, IMHO.

Both sides of the argument are right. I've never used one on a short action, so in the end my opinions aren't worth all that much. .
