Nice display item!

Am not 100% sure, Paul, but I believe you may be correct. Didn't think about the primers when first viewing the pics, but my first (and instantaneous) reaction to the bullets was "Huhh??"

My box states "Staynless" and that's why I didn't initially question the primers because the early Winchester "Staynless" primers were silver in color. From further research the 30 on the headstamp is not a caliber as I thought but year of manufacture. The only other photo I could find of just a WRA headstamp without the Co. was WRA 31 220 gr full patch with a copper jacket and "Staynless" silver primer made in 1931. The top label of my box confirms this on the bottom right where it reads 8-30 (August 1930).

Ditto, though I have a bunch of (mostly) sealed boxes of .50-70 and .45-70 to go with my guns. Never really acquired much for the Krag, and, it is all Frankford Arsenal stuff, in any event. The box under discussion is commercial, and I'm not sure that the rounds shown are those that it originally contained. Not sure they aren't, either - but someone will ultimately tell us, I'm certain.

I dug out WRACo Vol 1, thinking to find the answer, but found no reference, except that Winchester-made bullets were marked with a small "w" until 1932.  HWS Vol 1 reports that "Navy contracts for Cal .30 ball ammunition continued through the 1920s and into the early 1930s. An illustration shows a WRA 31 headstamp.   Later in the same long paragraph, the writer reported that some of the contract ammunition was released to civilian shooters via the National Board for the Promotion of Rifle Practice.  The last sentence in the paragraph reads "A late ball round, headstamped W.R.A. 30, has been examined with a nickle-alloy or monel metal primer cup - possibly for subcaliber use." 

In December 1961, I was assigned to inventory ammunition in storage at the Naval Ammunition Depot at Lualualei, Oahu.  I was amazed to find .30-40 cartridges in service.  They were Model 1925s, loaded with 172 grain M1 ball bullets.  The boxes were marked for subcaliber use and had Frankford Arsenal labels.  The cases were headstamped FA and dated from the late 1920s.

After all that, I don't think the cases are original to the box.  The box would have contained cases headstamped "WRACo".  After all that, the box and cartridges are still an item of interest.

Where was the W located on the projectile? I'm assuming it would be on the base and would be willing to pull one down for the sake of history and science! Scouring through other forums, cartridges of the world volumes, and auctions the "8-30" on the bottom right of the top label definitely indicates month and year of manufacture. Just as reincarnated stated I was expecting a headstamp bearing WRA Co. and was surprised to just see WRA. The 30 on the cartridge from all of my research also is a year of manufacture so the box and cases are at least from the same year but who knows if they actually belong together. I would certainly love to know. Pulling a bullet and posting pics of the bullet and powder may help?

The "w" is not on the base of the pre-1932 Winchester bullets.  It is stamped on the side in a very small font.  Must have done wonders for accuracy.  If there is a cannelure, the letter is forward of the cannelure.
