I have two rifles chambered for .257 Roberts...

I have two issues - Why is there no .257 Roberts data in the reloading section?

Why am I having such a difficult time finding brass for reloading? The only brass I find that is AVAILABLE is Nosler's premium product that is too expensive to use for practice rounds or general shooting.

AT

Gunbroker has several offerings of brass @ about $1 per case. I think brass is only produced intermittently by Win. and Rem.

Alec,

Go on the bullet manufacturers websites and you'll find lots of data.

Midway has Remington 257 Roberts brass on sale right now. Not the most durable, but it works just fine.

Matt -- "Unavailable - limited production."

About all you're going to find right now is Nosler.

I like these load books. Scroll down for the 257 Roberts.

I found some NOS brass locally for .50 c ea. last week. Little gold nuggets they are.

Your best bet for load data is older loading manuals. Most modern rifles can use +P data.

Ask Saeed why no data...EVERY reloading manual has data...you can use 6mm Rem, 7 and 8 x 57 brass in the interim or for all times...Hornady brass is very good...and the internet AND AR are FULL of reloading data for the Roberts, just research it.

Nope. 6mm Rem brass is based on the same case, but a tad shorter so they have different headspace. I have a 6mm case that I fired in mine, it is split in two in the middle. That's how I found out. Learn from MY mistake.. Dont do it! 7X57 works though.

So 6mm does not work to make 257 Roberts brass???
I would think if you full length re-sized it head space would not be an issue.
Is this the norm or just with your rifle?
Thanks for the info and clarification!

I think if you want to neck up 6 mm to the 257 you would need to neck up to bigger than .257, like 264 maybe .277. This should be enough so you can neck back down to the .257 and have enough shoulder to fire form.
Me, I like necking down, less steps. 7x57 brass is easier to find.

Don't want to get a big dust up going but I've used 6mm Rem brass(and clear up to 270/280 and '06 brass) many times to make brass for friends and relatives rifles for LOTS of reasons other than no factory 257 R brass....you have to do it correctly or you can have problems...fire forming with a low load or fast powder with bullet jammed into the lands will stop the problems for the most part, fill out the case properly and not worry about the small difference in base to neck junction difference. Having your sizer adjusted right and forgetting what the"normal" headspace numbers are and using YOUR RIFLES ACTUAL HEADSPACE will also go a long way to producing good brass...YA GOTTA USE MUCK-UPS to work out the proper methods.

NECKING DOWN is usually the best way and the way I go if possible and can compensate for MANY irregularities in chambers, reloading dies, etc but even that has some problems that need to be understood and compensated for. This neck-up method has been used for a ton of years...having to compensate for loss of components isn't something new...only new to many hunters.

What he said. Why would you want to go through the trouble of over sizing then sizing back down when you can accomplish the same thing by just sizing down 7X57? Just my .02 c. Also keep your eyes open at gun shows and in local adds and such, that's how I usually get my 257 brass.

My headspace is good and tight. The cases have a different datum line. If you were necking down the case then it would be fine, but since it is the opposite, a full length resize leaves the bad headspace in place. Using 7X57 brass instead not only takes less sizing steps, but there will be less work hardening on the cases as well.

I find it hard to believe 257 roberts brass is very hard to come by in the USA, i must have 300 pieces, but cannot mail brass south of the 49th.....FS

That makes sense!

Ive used 6mm brass back in the day, stuck a 257 bullet in it and fireformed it shot some 6mm factory in my 257 with good results....No problem in my several 257s..but mostly used 7x57 as its easier to come by and one pass thru the resizer and done..

I hear all manor of folks giving reasons not to shoot 6mm in 257 or 30-06 in 35 Whelen, or 257s in my 257 Ackley..but when I ask them to elucidate that come up with BS or "just because", or quote some gun scribe who decided on is own its a bad practice because the bullet it rattling out the barrel..copper is softer than steel btw...This practice has gone on for all of my 84 years and it was 80 year olds who taught me the easy way to get Whelen brass was to shoot cheap milsurp 06 in the Whelen.

Ray,we are on the same page.As to some of these "specialists",they are dumber than dirt.I have been caseforming brass for a long time.Hell; anymore I get more enjoyment out of the loading room than in the field.

In an emergency or a state of boredom, I will grab a 100 or 200 of 270 resized to 30-06, pull the bullets, take out the pin and resize them back to 270 and load them up..One of the reasons Im gonna love that annealer if my son ever gets it shipped to me..

Quit being a bunch of cheap fuggers and splurge on the Nosler brass. It's available. It is very good stuff and by the time you burn a bunch of powder, primers and bullets fire forming cases your incremental cost probably won't be that much.

I was in the same pickle a couple of years ago. Was set to buy some Prvi 7x57 brass and reform when I happened to stop by the Cabelas in Rogers, MN and they had Rem Bob brass in stock. Just because it isn't on the website doesn't meant it's not there.
Call around or just buy some 7x57 and rock on.

Ray,did John ever ship you the case annealer?If not,I understand, I too have a son;3 actually. R.

Cabela's has Nosler brass on sale in their online rock bottom prices section. Hope the link works.

Not yet Norm but he promised to, then promised to, then promised to..but he will sooner or later.

The crisis has been alleviated... was talking to my 'smith and he pointed me to Black Hills - they had some +P .257 brass in stock and I ordered a bunch. Friends also contributed some 100 or so once-fired brass. So I'm good to go.

Thanks all.

I think Buffalo Arms has some 257 brass..

If times get real hard I would sell some loaded 257 Robts loaded ammo, I overstocked myself with it. I would trade 5 boxes of WW 257 for 5 boxes of WW 25-35..

Just bought WW .257 Roberts+P brass, bag of 50 for 29 bucks at Grafs.

Well it turns out I got lucky with my
257 Ackley.

I loaded up some loads with max 257 Robts loads, in fact, several different 257 Loads to fireform, used book max loads..turns out they were all super accurate at sub 1/2 inches at 100 yards. this gun shoots anything..so as opposed to fireforming all in a day, Im going to hunt with them until they are shot up then go with the 257 Ackley loads..About 200 left now and Im ready to hunt coyotes, rock chucks and play at the bench. Even cull some whitetail if I get to Texas this fall..
