Is the short action Rem. 700 long enough to handle the .257 Roberts or .257 AI?


thanks,

Rob

The magazine is much shorter than I like. I have my .257 Roberts throated for a 3.00" OAL with 100 grain bullets.

I think at the std 2.775" it might work. However to me the Roberts case is better suited for a long action. A 115gr bullet is going to be taking up a lot of usable capacity. I treat a 257 like I do a 7x57 or 6mm. Set it up with the normal bullet base at the bottom of the neck.

Yes, it is long enough.

Some people prefer the longer actions for their longer magazines, but for factory length cartridges that is not necessary. Remington made their .257 Roberts rifles for a number of years only in the short length Rem M-722 rifles, and they worked just fine.

If I was going to go to the long action, I'd skip the Roberts round entirely and just get a .25-06 to start with. A person can always load the .25-06 down, but he can never turn a .257 Roberts into a full-fledged .25-06 level performer.

So, if you have a short action and want a factory Roberts performance level (which is plenty for most deer hunting), I'd say "Go right ahead."

I do believe you would do OK to use the short action. I do think you would need to extend the magazine box a bit and would be ideal for the 257 AI.

With that in mind, I think the Standard length Mauser is Ideal for the Roberts or the AI version.

Thanks, the gun is now chambered for .250-3000, I may keep it at that or go to the .250-3000AI.

I'll wait and do a proper .257 Roberts on a Mauser if the need arises.

Wildcat Emeritus P.O. Ackley himself told me way back in the early 70s that ALL the .25s were best with 100 gr bullets--be it the 250 Savage or the 257 Weatherby. Thus, with a 257 Roberts and a good 100 gr bullet the short action [2.800] mag is good enough. BTW! I get better kills with the 250 Ack with the old 100 gr Nosler Flat Base bullets than a friend does with a Roberts with 117s!! Also. For S%%%s and giggles-- load a few cases with the bullet of choice and run them over the chrony and then try the same cases with the bullet seated out and see what you get. I got about 20fps.
Aloha, Mark

Thank you all.
The gun is a .250-3000 right now, perhap's I'll leave it there or go to .250-3000AI and wait to do a proper .257 on a Mauser.
And I agree, if I was talking long actions I'd just go to the 25-06.

The 25 Souper would work well in that action.

No.

great fit ..
my 257 is on a springfield, and i load them short, STILL .. gun is 1/2 moa .. in fact, its better than i can shoot, and i don't see why not.

I have a SA Rem 700 originaly a 250 Savage, I bought in 257 AI. The Mag box was extended, and bolt stop modified to lengthen bolt throw. Very nice accurate rifle, but would not modify a a original 250 Savage in a 700.

You know, 35 years ago I had friends that did things like put a Chevy 350 motor in a Vega. It worked, but it really wasn't the best use of either the 350 or the Vega.

Mine wasn't the original .250 Classic, just used the barrel from one.

John, are you talking about the .257 or the .250AI?

That takes me back!!!! My first car was a pumpkin orange 71 Vega. It had the 4 cylinder aluminum block - it was a pile of junk. But to a 15 year old boy it was heaven on wheels. Some of my best memories growing up are with that car!!!!

I won't speak for John. But a Roberts potential is hampered already in the short action. Making a AI will add about 4 grs of capacity. Loading a 115gr bullet at the base of the neck vs factory standard will add 3.8grs. So my vote build a Roberts in a long action. If you feel you must have an AI only do it in a long action.

Remember guys I shoot more blown out wildcats and AIs than std so I'm not an AI hater.

Oops as I was cleaning up my late night spelling errors I noticed the question was .257 or 250AI. While my above comment stands for the Roberts I have never played with either the 250-3000 or 250AI.

but it was so popular that they made a small block in a vega, renamed molnza, as a factory offer. i had a v8 monza in highschool, with 4 speed, and dropped a 350 in it, replacing the original
