Q:
What do y'all think think of the .257 Roberts (AKA .257 BOB)? Good caliber? Apropos for all around applications? Or are there much better "mid-caliber" rounds out there? I read an article in a magazine (initials G&A) that was singing the praises of this round, but I have not heard much about it other than that article. Thoughts?

The .257 Roberts is a well-balanced cartridge offering the case capacity, selection of bullets from various manufacturers, and subsequent versatility to handle everything from varmints to whitetail or mule deer reliably. I owned two, a Ruger Model 77 and a rebarreled Remington Model 700, and both were a pleasure to shoot and to handload.

The 257BOB is on Par of the 243W,300Savage and Ammo is not in any Wal*Mart(hard to find) or Sport Shop. Its general a hand-me down Rifle in that Cal.its a White Tail/Black Bear Round as for a Mid-Caliber...JMO~7mm-08 has soft recoil like a 243W and works like a 270W!

My apologies; I edited my comment for the sake of accuracy or clarification to include the description "long action" for the Remington Model 700 I rebarreled. It didn't appear, due to delay, that the initial post was captured.

The .257 is a necked down 7X57mm, and is one of the most 'efficient' cartridges from a handloaders perspective. Velocity vs Powder burned
With the heavier, 120gr bullets it has been used up to elk and caribou with good success.
There is also a +P loading for modern rifles and the time honored .257 Ackley Improved that brings the performance of the .257 close to that of the 25-06.
In the Adirondacks, I have seen several black bear in the 500+ range taken with one shot from the .257.

I had a .257 Rob in a Ruger Lightweight some years ago. I didn't kill any deer with it but am sure it was capable of doing so. I traded the firearm before deer season came along,(I won the firearm on a raffle from a gun club). The gun didn't shoot that well but I blamed that on being a Ruger from the experience I have had with them and it being a Lightweight. I am more partial to larger rounds like the .280 and .308 for deer hunting and even my 300WSM.

The .257 Roberts is a good cartridge but unfortunately I don't think it's popular enough anymore for me to want to own one. I'd go with a 25-06 if you wanted a similar diameter bullet that's also a good mid range cartridge.

Mom has a Browning A-bolt chambered in 257 Roberts. I would consider it a little light for elk, but know of several people who have taken multiple elk with it over the years. She really likes shooting it and has taken many whitetails, antelope and mule deer with it. I occasionally borrow it from her if I'm hiking in a long ways to hunt, lightweight, low kicking, plenty of knockdown power for deer.

I have never owned a .257 Roberts, but I did shoot one that belonged to a friend of mine, and I was pleasantly surprised at the mildness of the recoil.
It was a real sweetheart to shoot.

No doubt The Bob is a nice cartridge but the 25-06 will do it all better and ammo is easier to find. I have a Kimber 8400 classic in 25-06 that is a beauty. It will reach a buck on the far side of an 80 acre pasture with no trouble.

I practice shooting with my Ruger .257 Roberts. Cheaper to shoot and easy on the bones. A very capable deer caliber as well. Anything shooting a 100 gr Barnes TTSX at 3,000 fps is a deer getter.

I have one in a Ruger Ultralight, my daughter one in a Savage, and properly handloaded they are deer thumpers. Mine doesn't like 100 grain fodder so I am currently handloading 120 grain Remington Corelokts for both rifles. I think it's a better round than the .243 or 6mm due to the availability of heavier bullets.

I echo Del's comment. The 25-06 , as a 25 caliber, doe the job a bit better, but with a bit more bang and a bit more recoil. The ammo for the 25-06 is much easier to find. I own a 257 Roberts, a 257 Ackley Improved, and a 25-06 and like them all. Have taken deer, pronghorn, and elk with all three. My largest Big Horn Sheep was taken in Wyoming with my 257 Ackley Improved. One shot penetrated both shoulders, leaving an exit wound three inches in diameter. The sheep lunged forward ten feet stood looking puzzled for a moment then dropped. Frankly, I was very surprised.

I recently bought an older Ruger M77 in .257 Roberts but I haven't even had a chance to shoot it yet. I did a clean up and scope mount on one that my friend has in 25-06 and was impressed with the rifle. I am very much looking forward to trying it out.
WAM described the load am I hoping it likes. My son will be of legal hunting age in 5 years and I hope to pass it along to him someday.

Anyway from what I gathered from the posts the .257 BOB is one of those undeservedly rare calibers, and if I can find one a gun show with a lot of ammo for a good price I might go for it.
Thanks guys!

The .257 Roberts is not the equal of the .25-06 or .257 Weatherby in terms of velocity. However, the light bullets common to all three do not buck the wind at extreme ranges very well and all the quarter bores should be kept to sane ranges, particularly in the often windy West, except by the most practiced shooters in those conditions.

mspl... As you might know by now, I'm a big fan of the quarter bores for all around North American hunting from little varmints to our biggest mule deer. Among those, the .257 "Bob" is an outstanding cartridge and will do it all. It is a .243 on steroids.

That being said, I prefer the 25-06 instead. I get just a little more speed from each bullet. I can load them down to "Bob" velocities if I desire (but I rarely do except in heavy brush conditions). With varmints and fast running game, speed is king! The 30-06 family of brass is easy to come by and a person can find ammo on any store shelf in America (although I've still never fired a factory 25-06 round).

WAM, not sure what you consider sane ranges. My 25-06 deer bullets fully penetrate the biggest of muleys at 500 yards and flatten them just fine. The 10 MPH wind drift of my 100g 25-06 Sierra Game King (I've grown to like its accuracy and lower velocity expansion) is 14.8" at that range while that of the 140g 7MM Mag is 16.6". Quite similar actually in bucking the wind. If you are shooting at that range, wind correction is necessary with any caliber. If you use good "very low drag" bullets, most calibers buck the wind quite well at that range. Both calibers penetrate well at that range and when comparing carcasses from both, I've observed that "dead is dead" in both cases.

The 25 caliber 115g Berger is even better and of course hits harder at even longer ranges. I'm quite comfortable with the 25-06 out to at least 500 yards for deer and go to my .300 Dakota from there to 1000 yards for anything up to elk sized game. I'd feel comfortable shooting deer with a "Bob" out to 400 yards.

My favorate quarterbore from a performance perspective is the 25-06 Improved traveling at .257 Wby speeds with a LOT less powder and free brass that head-spaces well. Generally more accurate than the .257 Roy for those 700 yard p-dogs. I finally quit shooting them though once Remington came out with the 25-06 because that is actually fast enough it seems and it saved me the fire-forming step.

Hmm,
My 7mm mag has a 10 mph, 90 deg wind drift of 13" and the .300 Roy has 10.5" at 500 yards. I calculated the 10 mph drift of a 100 gr Ballistic Tip at 3,300 fps to be a bit more than 17.5 inches. It's all about BC and speed!
