A Classic Returns in .257 Bob

Often overshadowed by the 6 mms, the .257 Roberts is a .25-caliber round that started as a wildcat, but is now being reintroduced in the Model 70.

The 1920s were a fascinating time in American history. Full of pride and bravado after saving the world from the Kaiser, Americans led the way in the industrial revolution, as well as a cultural upheaval. Shooters were caught up in the mix, too, with gunnies everywhere experimenting with new cartridge designs. One popular experimenter and writer of the day was Ned H. Roberts. He, as well as some other experimenters, was consumed with the idea of what were called “quarter-bore cartridges,” cartridges of .25 caliber. The idea was to have one rifle capable of being shot all day at varmints, yet have enough power and range to take deer-sized game. Roberts—after much experimentation—settled on the 7x57 Mauser as a parent case for his quarter-bore brainchild.

Custom rifles from Niedner and Griffin & Howe became available for Roberts’ wildcat in 1928 and were quite popular among hunters. In 1934, Remington brought the cartridge into its factory fold changing Roberts original 15-degree shoulder angle back to the parent’s 20-degree angle, naming the former wildcat the .257 Remington Roberts and chambering the company’s Model 30 bolt-action rifle for it. Winchester immediately chambered its Model 54 for the cartridge, and when it came out with the Model 70 in 1936, the .257 Roberts—as it became known—was one of the original chamberings. With the exception of World War II when all armories were supporting the war effort, the .257 Bob—a common nickname it received—was somewhat popular.

However, by the mid-’50s the 6 mm cartridges began to show up, casting a bit of a shadow over Ned Roberts’ cartridge. A big part of this was due to the fact that Remington kept the factory loads pretty mild in deference to some older receivers that weren’t up to modern pressures. Factory loads replicated the ballistics of the .250 Savage. Handloaders were able to get all the capabilities of the .257 Bob, provided the rifles they shot were strong like the Remington and Winchester. Too, part of riding the wave of a fad is the inevitable slide off the crest due to boredom. Fad shooters are just like fad anything; they are in a perpetual search for something new to stimulate their minds. Eventually the gun manufacturers quietly dropped the .257 Roberts from their chambering menu, replacing it with the 6 mm Remington and .243 Winchester. Because so many rifles were out there chambered for the Roberts’ cartridge, ammo makers continue to make occasional runs.

Winchester discontinued chambering the Model 70 in .257 Roberts in 1959. In the mid-1980s Winchester Ammunition began offering +P loads in the .257 Roberts at 5 percent to 7 percent above the Remington factory load and featured a 117-grain Power-Point at 2,780 fps from a 24-inch test barrel. Browning/USRAC also did a limited run of the Model 70 XTR in .257 Roberts. This Model 70, along with most rifles chambered for the .257 Bob, are made with 22-inch barrels.

Recently, the renewed Winchester Repeating Arms Company made a special run of 500 Model 70s in .257 Bob for Cabela’s. I saw it at this year’s Media Day at the SHOT Show, but the frigid gale blowing that day made shooting this new chambering futile. I’ve always had a bit of a soft spot for the .257 Bob, believing the heavier 117- and 120-grain bullets to be a good performer on lighter game like deer and antelope. Cabela’s Joe Arterburn knows I am a sucker for Model 70s, so he sent me one to evaluate.

The Cabela’s rendition of this chambering is thoughtfully done in the Featherweight platform—it features a 22-inch barrel tapered to a Featherweight profile to reduce weight. The stock is A-grade fancy walnut, checkered to 20 lpi. Because this is a premium rifle, the bolt is jeweled, and the entire rifle is polished to a deep luster—both wood and metal. It is equipped with Winchester’s MOA trigger that some like and others disdain for its departure from the original design. At a bare weight of 7 pounds, it qualifies as a Featherweight in terms of Winchester Featherweight nomenclature, though lighter rifles are made today. My test sample came with a Cabela’s 3x9 scope already on it, swelling the rifle’s weight to 8 pounds, 9 ounces.

The wet, cold and downright nasty spring weather we have been enjoying postponed my range time with the new Model 70 a couple of weeks. Once there though, the rifle didn’t disappoint. My first shots using Remington Express with a 117-grain Core-Lokt bullet loaded to the same mildness Remington has always loaded this cartridge fell into a 1 3/8-inch group. Ten rounds later, my chronograph confirmed the mildness of this load showing an average velocity of 2,565 fps. Completing the test with the Remington load yielded an average group size of 1 1/8 inches.

I then switched to some semi-custom ammo from The Hunting Shack, out of Stevensville, Mont. Under the trade name of HSM, this ammunition is loaded with premium bullets and often powders that are not available to most handloaders. In this case, the .257 Roberts cartridges were loaded with Berger 115-grain HPBT Hunting VLD bullets. Though this was my first experience with .25-caliber Bergers, I have loaded and now regularly use the 130-grain HPBT Hubting VLD bullet in my .270 Winchesters, and they are superb in terms of accuracy and terminal performance on game. Loaded to a much zippier 2,973 fps average, this ammo was clearly the front runner with groups averaging 7/8 inch.

Several things come to mind as I ponder this rifle. First, I wish it was available 35 or 40 years ago when I did a lot of backpack hunting. Its light weight and mild recoil make it an excellent choice for the mountain hunter. Secondly, in its modern loadings or handloads, the .257 Roberts has a better downrange trajectory and hits harder than the .243 Win. or 6 mm Rem. And finally, you younger hunters take some advice from an old man that knows better now: By the time you reach my age this rifle will probably have acquired another generation of dedicated aficionados and be worth more than you paid for it.

Please, for heaven's sake, don't call it the Bob. 'Sounds like some obscure, stumpy wildcat. Drop the '257' if you have to be novel. Saying 'Roberts' doesn't take that much energy!

I have a pre 64 model 70 Winchester in 257 Roberts Caliber and was told by Bass Pro that I can't shoot +p ammo out of it ?

A 'common nickname' ? I've been shooting for nearly 40 years and first heard about the .257 Roberts from a hunting buddy soon after I started. I never heard of '257 Bob' until I read this piece!

Meh. Another expensive limited edition Cabela's rifle. That cartridge was meant to be shot, not put in a dress gun. I hope Winchester gets its act together and gives us a standard SA featherweight in 250-3000 for the round's centennial in 2015.

It was the frist rifle I took my first deer with, off hand at around 250 yards. Low recoil, it is very nice caliber to shoot. It is still my favorite rifle caliber. I enjoy target shooting with it. I also use it to help retrain myself when I start to flinch from the larger caliber rifles.

I have loved this cartridge for over 30 years since getting a Remington 722 in 257R as I call it and is now my varmit round using 75gr VMAX and zipping at 3600 fps. Very flat out to 300yards and 3/4' groups in a good rest. I wish there was a 700 model out there.

I have a custom .257 Roberts that I had made in the 1960s. Full 30-06 length action so the heavier bullets did not have to be seated so deep in the case. It was built on an FN supreme (400) action and a myrtlewood stock. I bought the blank in Oregon. It has been used to take most of my deer.

I was given a 1930's Winchester Model 70 (scoped) in .257 Bob by my father-in-law, who got it as a young man for hunting in W.VA. He kept it in excellent condition. It was his pride and joy, and is now mine as well. Sweet gun. I no longer hunt, but my sons and I love punching paper with it at the range. In addition to Cabela's, I have found .257 Bob at Dick's Sporting Goods here in SE PA, as well as two other local shops. It has been scarce, so I am happy to see its return. Hopefully, it will be easier to obtain.

One of the first 'big rifles' i had was a Remington .257 scoped with a Weaver K-10. That was in 1962. Head shot a groundhog at 310 yards. Then left and went into the service for 30 years and like all things that operated great, it got away from me somehow. Hadn't thought about that rifle in many years. It sure was one sweet shooting rifle and ammo was 11 cents a round i believe... How the times have changed.
