Remington 700 Classic 257 Roberts

I was wondering if the receiver used was the long action or short action. The reason for the question is to determine if I can reload ammunition to an OAL that exceeds the 2.8 inches magazine that the short action limits this cartridge to. I know that if I can use an OAL close to 3.0 inches, I can seat the 117 and 120 grain bullets further forward and get more case capacity for powder. Using a slower burning powder like 4831 can get me up to 25-06 performance out of the 257 Roberts.

Some Winchester 70 "short actions are actually long actions with a magazine box spacer and shortened follower.
Remington may have used the same method. If so, a simple mod can allow longer OAL ammo.
What is your H4831 load for the 120 grain bullets?
I will say to be careful hot rodding the BOB round. Some casings are +P, and some are not. The Bob was not meant to be a 25-06, and trying to turn it into one could have unwanted results.

The Remington Classic in .257 Roberts was a short action. Remington did not try to use Winchester's idea of a long action with spacers at all.
If you want extra room for seating bullets out, try the Wyatt's Outdoor Products:

You could also switch to Detachable Box Magazine feeding and get an even longer OAL but it will require that you modify the stock.
Realize that in the world of Bob, this little increase will not result in anything significant as far as velocity is concerned. The Bob will kill nearly anything on this continent with the proper bullet and proper placement.
Best.

This can be a very nice solution to the magazine length discussions since many of the military Mausers used the 3.228" magazine length. This will allow for virtually any bullet design your heart desires with room to spare. Besides, everyone needs a classic Mauser in .257 Roberts (or AI).

*The Three Inch was originally produced by putting a .30-06 magazine follower and bolt stop in a Model 70.
**The Roberts 3.3" called for reaming the chamber throat to accept a 117 gr spitzer seated with the base of the bullet at or above the base of the case neck
Thank you for your expertise, again. Looking at the situation, I will leave well enough alone. I will limit myself to 100 gr bullets to keep me from making a mountain out of a mole hill.
Later, may be I will find an old mauser or remington action to make a longer OAL 257 rifle. As I get older, I find I don't have the time to play with the toys I have any way.
Again, thanks for all you advice and suggestions, they are very much appreciated.

If you do go that route, go with the Improved Bob chamber. It will do exactly what your looking for.
In the meantime, if you want a serious deer thumper, and will work for Elk too, give the Barnes TSX, and TTSX bullets a spin. If you get good accuracy, their performance is absolutely nothing short of amazing. Especially in the lighter caliber's.

I have a Mannlicher Schoenauer 1950 in 257 Roberts.
The reload I use is
1) R-P cases trimmed, primer pockets reamed, and flash holes deburred
2) Nosler 115 grain Ballistic Tip (seat half way then turn case 180 degrees then seat all the way)
3) 45-46 grains H4831SC (settled on 45 grains H4831SC)
4) Federal 210M primer
5) OCL 3.090 inches with half turn crimp using Lee crimper
The cartridge looks really long compared to the factory cartridges where the bullet barely pokes out of the neck. I always thought
that was because they had to work through a Rem 722 short action box magazine.
The second 257 Roberts I had was a new stainless Rem 700 with a classic stock. Never did reload for that one. One look at the rifling and chamber and I shipped it back to Remington. The rifling had reamer chatter (or some kind of tool marks like rings) from one end to the other and the chamber was gouged out in places. Remington sent me a 700 LSS in 7mm/08 as a replacement.
The third 257 Roberts is a custom Ruger 77 II all weather with a long action and Shilen Select Match barrel. The load parameters are the same as above for the 1950 MS except
3) 41.5 grain IMR 4350
5) OCL 2.900 inches with a half turn crimp using the Lee crimper
The Ruger 77 is just a little bit more accurate than the 1950 MS.
