New Bob coming my way. Besides the obvious availability of Win Rem brass is their a better option for quality brass such as necking down Norma 7x57? Alan  | ||

Yes I use the same brass and I find it excellent. My 257 Rob is working great with the above WW brass, 41.5 grains of IMR-4350 and 117 grain Sierra SPBT's, very accurate, 2815 fps and works great on big mule deer, antelope and coyotes. I'm hooked on it. | |||

 But one can also use Frontier brass from once fired Hornady ammo....It's made by Winchester! /////////////////////////////////////////////////////////////////////////// "Socialism is a philosophy of failure, the creed of ignorance, and the gospel of envy, its inherent virtue is the equal sharing of misery."

I've been using the Hornady brass from their premium loads - seems to work well. I have some Rem and Win brass too............ | |||

Have an acquaintance in Australia who works for the Australian Defense Industries (ADI whom makes Hodgdon powders) who is sending me some unfired yet older WW headstamp in the Win White boxes. Should add a little more nostalgia. Alan | |||

It might be nostalgic but if not the +P case you will not get the longer life with hotter loads. It is neat how so many agree with the Winchjester +P case. I also had good luck with the once fired Frontier cases! Great minds I guess or perhaps weak minds??? PA Bear Hunter, NRA Benefactor | |||

I'm obviously in the minority but I use Remington brass. Never had any issues. | |||

not being up on the reloading facts, what does the +P case mean and if you were reloading should you get the +P cases over regular cases if you can ? | |||
|
| One of Us |
The only +P cases I have are from factory loaded ammo that was loaded to +P pressures and are not a quality of the case that I'm aware of. As far as I know....the cases are all the same and only the pressures that they are factory loaded to are labeled +P I'm sure some folks will disagree with this. /////////////////////////////////////////////////////////////////////////// "Socialism is a philosophy of failure, the creed of ignorance, and the gospel of envy, its inherent virtue is the equal sharing of misery."

We can buy W-W .257Roberts +P unprimed bulk brass here in Oz. Due to not enough 7x57 brass, I have to neck it up with an expander button in a 7x57 F/L die to make 7x57 brass. It is top quality brass and I have had nil problems with it. | |||

Sam184, Well, In this case it's going to mean one of two things. Either +P means the cartridge is loaded higher pressures and the case itself is built to identical specs as a "non" +P case. Or, it means the cartridge is loaded to higher pressure "and" the the brass itself is built a skootch thicker throughout the web to tolerate the higher pressure. I've not seen a definitive explanation yet. Alan | |||

The WW 257 +P case is beefed up to withstand higher pressure. Cut one in half and compare to a standard WW 257 case; it is stouter with thicker brass. Some +P marked ammo (not WW 257 +P) just indicate a hotter load,i.e. 38 Spec +P, 45 ACP+P. PA Bear Hunter, NRA Benefactor | |||

I can't prove this but believe it completely.....That said...I'd not be afraid to build +P loads on standard Remington cases.... FWIW that's all that is available....at least from Midway...Winchester +P and Rem UMC /////////////////////////////////////////////////////////////////////////// "Socialism is a philosophy of failure, the creed of ignorance, and the gospel of envy, its inherent virtue is the equal sharing of misery."

I'd be delighted if someone who believes that there is a difference in non +P brass and +P brass would post a photo of two sectioned cases illustrating the alleged difference. | |||

My buddy who works for ADI emailed me back and said the info his ballistic lab has says the non +p Remington brass weighs 170.7 gr and the +p Win brass weighs 174.9 gr. Alan | |||

Oranges and grapefruit look a lot alike but one is usually larger than the other. The only meaningful comparison is between Win +P and Win non+P. The 3.8 grain difference in Rem and Win could easily be the difference in the length they are trimmed to, not in their web thickness. Even so, 3.8 grains is deminimus in terms of brass strength. Even then, the weight is only an indicator -- weaker brass having thicker walls near the shoulder and thinner walls near the web could easily weigh more than much stronger brass with thicker walls near the web and thinner walls near the shoulder. | |||

After 40 years with a 257 AI ,I've had (virtually) every brand of brass fail-- NONE at the primer pocket or base (its self)-- Most at the area near the shoulder- & some about 1/2 " up from the base. If I had to single out the worst batch of brass I ever had ( loss during fireforming) it was a single lot of NORMA ( much to my surprise) other lots have done well. Overall, dollar for dollar, the run of the mill Remingtons have held up well; as have the Federals. If I had to single out my failure rate without respect to individual lots- the Winchesters have by far had more failures. Once past the 1st 2 loadings most brands have held up about equally. My standard hunting load for many years was a 120 Norma, over 50 gr of H4831. The old girl remains accurate after too many rounds to remember.

I read this post as supporting the statement that any .257 Roberts brass can be used in +P loads. /////////////////////////////////////////////////////////////////////////// "Socialism is a philosophy of failure, the creed of ignorance, and the gospel of envy, its inherent virtue is the equal sharing of misery."

Many years ago (like 35) I came by a single box of virgin Norma .257 Roberts brass. The heads were very soft and primer pockets loosened after only one shot with the same load that was sustainable in WW brass. Norma earned a reputation in those days of producing very soft brass. Norma even felt compelled to defend their soft-headed brass in magazine articles as being hard enough to withstand SAMMI pressures. Whether that was true or not, Norma brass would give up the ghost far quicker than WW or RP. I'm told that Norma has long-since moved to a harder-headed brass than they produced in those days, but having had no reason to spend double the money to find out if their brass now equals run-of-the-mill American brass I wouldn't have personal knowledge. | |||

Only Federal on a Blue Moon,can rival Norma for softness. In Bob/Better Bob,I prefer R/P to all...even if I have to neck up 6mm to get there. | |||

About ten years ago, while criusing a gun show looking for treasures,  I came across a scoped Ruger #1B in .257 Roberts. The price of $400 included 100 rounds of Norma factory ammo and the dies to load the brass. Needless to say it went home with me.  It turned out to be properly sighted in and I shot a very tight groups at 100 yards with the first five shots. (.80") Five more shots were just a hair larger, probably because it was ahot day and the barrel hadn't cooled down all the way. I set up the dies for my press and reized the brass. When I went to prime the brass, the primer pockets were quite loose. I dunno how old that ammo is, but I haven't seen it on Norma's list in a very long time.Paul B. | |||

Bought some WW Super brass the other day. Had to "really" clean out the pockets with my Sinclair #8000 tool. They're very shallow. Alan | |||
