Guys, I need a new project and have been looking hard at a .257 Roberts. My new Barnes Manual says that the little Roberts will drive a 100 TSX at 3126 fps from a 24 inch barrel with 46.5 grains of Ramshot Hunter. Great velocity and not much recoil. What's not to like. What do you think? What are the pros and cons of the Bob?

I just bought a box of TTSX's for my Bob. Eager to try them out. I usually don't push mine that fast as it seems to shoot better with a bit milder load but each rifle is different.

Pros of the Bob: Too many to list.

Cons of the Bob: Your friends will constantly badger you to sell it.

Clem:

What kind of brass are you using? Is is standard stuff or pressure+?

I've been using Winchester +P brass. I have never tried anything else so don't know if it makes much difference.

It should be doable. I'm not using Barnes bullets.
I'm averaging about 3050 fps using a max load of IMR 4895 and 100gr Nosler SBBT from a 22” barrel.

The 257R is a great round. I toyed a little with the 100 TSX but I like lead so I settled on Nosler BTs and Accubonds. You won't have any problem getting 3000+ fps out of a 100 grain bullet. H4350,IMR4350 and HV100 have all worked well for me.

Mine is a Kimber Select 84m. The only kill on that rifle was by a friend that borrowed it for a hog hunt. The 115 NBT went strait through the shoulders of a 100lb hog. He went 20 yards and died.

The 110gr Accubond in .257 would be the one I'd try. It was stellar in a 257 Weatherby I had.

Dave, did you fall off the 338 ROOOOOGER bandwagon already??? :-)

John Barsnes likes the 100 TTSX and Hunter combination as well. So, I tried it. With 47 gr in my 24" Krieger I get 3176 fps, 21 ES, 8 SD and 3 into .76".

Ql calls that load at around 55,000psi. Over the std but below the +P. Years ago when I tested the capacity of the two In my measure they were the same. I've also seen reference that the +P case was thicker. I no longer have either to retest.

Question I raise is if the 6mm is loaded to 65,000 in a modern rifle why not a 257 Roberts? I load my 6mm to 63-65,000 I also have no issue with taking the wifes 7x57 to the same range. The 6mm, 257 and 7x57 are basically the same case.

I agree with Biebs the 110 accubond works fantastic in my 25-06.

The one downside I can think of is that the 257 is a medium length cartridge, so getting a proper action could be an issue. Personaly I love the X57 case and an M-48 Mauser action works very well for them.

My 257 AI matches 25-06 balistics with a 115 gn bt, she's a peach. But sometimes I wish I just went with a plain vanilla Roberts. I dont have feeding issues, but I did have to do some modifying to the action. Nothing wrong with a 257 rob at all, in fact my Dad often stated that his was his faviorite deer rifle of all time. They are a pleasure to shoot and very effecient for deer sized game.

No way Biebs. I was at the range on Monday shooting the .338 RCM. It is a fantastic little gun. I just need a new project. I think I am going to trade my .35 Whelen Classic off on a Ruger in .257 Roberts.

How is the .577 shooting?

TX, you are correct. I did start this thread in the wrong place. Sorry.

Dave,
I have no experience with those bullets.
My 257 Robts. loves 110 Accubonds.
Just passing it a long.

I've got an older .257 tang safety Ruger.
Gets along real well with 100 gr N.P."s & IMR 4350. Nice to carry and gets the job done.
Only con (if it is one) Just a bit small for Elk.........

I'm loving my Roberts, Ruger tang safety.

115grn nosler bt and 45.5grn H100V.
117grn Interlock and 43grn RL 19.
100ttsx and max load of RL 19.(47grn if I remember)

It's nice on both ends and has given me no complaints in the deer killing dept.

Common 117 to120 grain cup and core bullets have proved adequate with the .257 on a number of mule deer. Also took one with an 87 grain bullet at 25-35 energy level. roger roger

Hard to argue with that.....it's history speaks for itself.

Pros: 257 Roberts is as good as any.
Cons: Brass isn't always easy to find, and loaded ammo is nearly non existant.

???

I load for mine, my boy's, etc, etc--
Hmmm- a total of 7 257's

I have NO problem finding components or loaded rounds--

Dig through a mountain of once fired brass.
The tow factory rounds most likely to have blown primers are the .25-06 and the 6mm Remington.
They are loaded really hot from the factory.

I've had a tang safety Ruger since '72. I've killed a bunch of stuff with it. I've had better luck with 100 grain bullets, as far as accuracy is concerned, than with 120's. It's killed a lot of deer with all kinds of bullets, even the old Winchester Silvertips. I thought they were the best bullet in the world for a few years, but I got over it. I've had good luck with standard cup and core. Right now, I'm using the old blue demons that Barnes made. They shoot well, less than MOA, and zip along a between 3250 and 3300 fps with H4350. While I love the gun and caliber, I really wouldn't use it for elk. I have too many rifles that would be better in my opinion. My rifle is also a serious groundhog killer with the 75 grain Vmax at similar velocities.

Funny I always thought the 257R was a short action length since the COL is under 2.8. I'll have to check my Kimber 84 again, I thought it was a short action.

I believe that most factory 257R were short actions. I agree with Wstrnhuntr that the 257R is better suited in an medium length action with the bullets seated longer. Just like it's parent the 7x57.

Yeah, I was just being a little bit of a smart ass. I actually don't think you gain much at all from an intermediate action when it comes to velocity. I'd be shocked if you get much more than 50fps advantage.

My wife and I have been using a Ruger Model 77 Ultra-Lite for about 12 years now. @We have had excellent results with 117 grain Core-Locts and 115 grain Barnes TSX.

I hjave never understood the debate over long and short actyions, as I believe the normal shooter will never shoot enough to be able to tell the difference.

Love my .257 Bob. I prefer a 117 SGK over 44.0 of H4350...2825 fps and it's a heckuva killer.

I've loaded 100gr. TSX's over 47.0 of H4350 and the accuracy is superb. Somewhere around 3000 fps in my 20" bbl rifle.

Either would work just fine on deer. Or hogs that need to have their heads examined.

I'd say 50-75fps depending on bullet. Short bullets probably not much if any gain. That is just what I saw in a MKX length action playing with the seating depth. The shorter OAL had a longer jump so maybe I was able to get a little more powder in before pressure signs.

In the real world the gain won't make any difference. But if you have a medium action or even a long it is free velocity. Heck people jump through all types of hoops AI's long throats, wildcats etc all for an extra 50-75 and this one is laying there free.

Too bad the Roberts was never loaded to it potential from the factory.

100gr at 3000 is pretty easy to do.. but 2900 is alot easier on the brass ...

bob's aren't loaded, factory, soft due to brass, fellas, its due to the (now) questionable actions they are frequently built on ...

Ruger Hawkeye in .257 Roberts is on the way. I'll let you know how it shoots after I had a chance to wring it out.

This is from the other end of it's use... I use the 117RN out of a 20" carbine for hunting the "woods"....quick killer!
