I was sorting through some .270 Win brass that someone had given me some time back. I was separating them by brand and I have a few cases that were stamped W.W. SUPER and a few that were stamped SUPER SPEED. Are these both Winchester brass?

Welcome, they are both Winchester. the super speed head stamp was before 1980.i use both and I seperate the two. case volume is a little different.

Thanks. I have a surplus of .270 Win brass and was going through them making an inventory. People who gave these to me over the years probably didn't realize their worth or at least their worth to an individual who reloads.

The various Winchester ammos through the years have a multitude of headstamps.

Super Speed is like pre 1970 on Winchester ammo.

Super-X was the same era on Western and then was the standard on Winchester when they stopped selling Western

Winchester was on factory ammo after that.

WW Super was bulk brass and also on ammunition.

Winchester and WW Super are both bulk brass and loaded ammunition.

Also the military ammo with headtamps of WCC and the very early WRA, which was also on commercial ammo in the 1930's etc.

All is good brass; I am not sure about case capacities or internal design except the mil brass for the large calibers is heavier and requires a one grain reduction. The 223/5.56mm cases are not heavier in military headstamps.

The Winchester and WW Super 257 Roberts brass is not as heavily constructed in the webbing as the Winchester and WW Super +P

Years ago Winchester made the Frontier brass for Hornady and I was the same as Winchester brass of the same era. I do not know who makes Hornady brass nowadays.

These are my real life experiences with these cases. I don't claim then to be gospel, but pretty accurate.

. . . repetition of an assumption made by many and never illustrated to be factual.

Cut them open. They are very different.

Nowadays Hornady makes their own brass in Grand Island Nebraska......and it's some pretty good stuff.

As for the +P 257 brass (never owned any), I have got some hellacious pressures and velocities out of the old stuff, so I can't imagine it needed any improvement. Was never weak to start with; just underloaded. I would like to see some.
The various makes, including WW, and SS, do vary in weight though.

I have read it in one of my reloading manuals when using loads in R-P, Fed, or regular WW Super 257 Roberts to reduce the charge 1 grain if using WW Super 257 Roberts +P.

I cut two in half last night and the +P is .010" thicker in the web from the regular WW Super. They are both heavy on the sides; darn strong cases, and these both have a few reloads on them.

Can you weigh some and tell me what the +P brass weighs?

I dugout my brass and scale. I don't know how valid the numbers are as I do not know the history/trimming etc of the regular 257 Roberts brass varieties and my sample size is small. Also it appears that I cut up my only WW Super regular 257 Roberts.

1. Super-X: three cases all were 183grains

2. WW Super +P: three cases all were 175 (these were all trimmed to nominal and then once fired.

3. Rem-UMC: one case 171.6grains

4. Super Speed: one case 163.2grains

dpcd:

FYI , my records indicate the following weight ranges for once-fired and trimmed .257 Robt brass from factory loads bought in the mid-90s (n = number of cases):

F C +P red box: 168.7 - 172.6 gr. (n=97);

F C +P Premium: 181.0 - 183.6 gr. (n=98) (Note: there is no visible difference between the two F C lots of brass);

FRONTIER +P: 173.3 - 175.7 gr. (n=18);

R-P new lots: 165.9 - 173.0 gr (n=197);

R-P old lot: 176.1 - 183.9 gr. (n=28) (Note this lot has a larger headstamp font);

SUPER SPEED: 161.1 - 165.4 gr. (n=20);

W-W SUPER: 159.3 - 163.8 gr. (n=36); and

W-W SUPER +P: 170.8 - 175.6 gr. (n=80).

Wow! And I thought I was anal expulsive (or is it anal compulsive?).

LOL that is the first and most likely the last time I weigh brass.

Gotta find something to do related to shooting when it's well below zero, the range is buried in 6 feet of snow, and the ammo boxes are full to overflowing with reloads!

I would tell you to move to California where I have been shooting this past week in a T shirt but this place has been taken over by gun grabbing communists (they call themselves Democrats).
