Late last year I was able to pick up a couple of boxes of Winchester WW1 era 175gr FMJ roundnose ammo. In truth my plan and intent was to just get the actual bullets, and reload them in modern brass etc, since no one makes roundnose FMJs anymore. Anyway these two boxes weren’t cheap, between the two well over 100$ but I had hoped they would be salvageable boxes. One was heavily wrapped in plastic, and so the ham-handedness of its opening (the red box) wasn’t obvious until I drove the 300km back home…
Anyway it was interesting to simply look at the ammo the boxes contained, and I thought a few words might be in order.
Firstly, this stuff is NOT rare, don’t buy it at ridiculous prices if you just want a collectable. If you look around (libertytree for example) you will see boxes of this stuff selling for 15-20$ in the US. Sadly that is not Canada, so as much as I would love to buy a few hundred cheap rounds and salvage the projectiles it isn’t an option really. But as a collectable, these would be over priced at 40$ Canadian (IMHO).
If, and I mean IF the box is in great shape and not torn open half-assedly, then I would say a fair price would be 75-100$ just for a collectable box, but otherwise buying these is really just for show, and make note of what you are likely to get.
First up is a plain brown box, I got these cheap-ish because of the collapsed rounds, and the advanced state of decay. A lot of split necks, some tarnishing, but truthfully both of these boxes had beautifully polished brass, just lovely looking casings.






























The second box is a red lable, the contents showed no collapsed rounds, but on looking closely some neck splits were noticeable, and internally they were not much better than the last box.


































When pulling a few rounds apart the internal decay is obvious, some clumps of powder, but more so corrosion on the inside of the casing, and end of the bullets.







I cut a round in half to see inside better:
The primer/case head area








And the upper half, looking inside the neck / shoulder area









Anyway these rounds are still out there if you look around a little. Just be wary of them, even though some looked good on the outside, I wouldn't be keen to try actually firing them.
 
Split necks seem to be very common with Winchester ammo of that vintage. I had a box of 8x57 in the same style of box and the neck of every one had split, and you could pull the bullets with your fingers.

Test the bullets with a magnet. It's likely the jackets are of nickel or some other alloy, not steel. European stuff of the same vintage ( FN & DWM) will have nickel coated steel jackets... just in case you want to shoot elephants with them.
 
The ammo from the first batch appears to have a bright shine for it's age. It seems someone may have hand polished the rounds at some point as I have done this with older ammo that I was concerned with feeding and extraction due to corrosion. Anyway you were after the projectiles so this is just an observation on my part. Phil.
 
Tumbled rounds?

I have ammo of a similar vintage and I agree it must be. An interesting and useful thread, as it show the effects of time (known) and storage conditions (unknown).

Is that a "natural" decomposition of the powder, or did unfavourable storage conditions cause or at least accelerate it (moisture and/or heat)? Does brass simply crack with age? If so, why, and do variations on the brass alloy contribute to or prevent that? I say that because I have some very old brass that is uncracked, and more recent that it cracked. I also have a large lot of loaded ammo some of which is cracked and brittle and others that remain malleable - same alloy (presumed) and same age and storage conditions (known).

It would also be interesting to see if the primers have been affected, i.e. are they still live. A possible source of powder contamination is of course the primer, noting the corrosion at the casehead in one photo.
 
Saw a case of Winchester 30-06 that came from the Dominican Republic, it was similar but worse than that, alas the asking price was too high for me to buy to salvage the bullets.

Well I pulled apart about 30 of these today. The powder smelled sour/pungent, worse than say, bad asprin, but similar. Almost every bullet shows signs of corrosion on the base. Some had chunks, the size of a primer, of green corrosion that came from the base of the bullets. I suspect even the bullets may not really be worth trying to reload. The powder for the most part looked fine, but one or two rounds looked like they had broken down.
I suspect the neck/shoulder area where the corrosion at the base of the bullets was is due primarily to tension and the corrosion/reaction inside the casing with the bullet.
From what I have seen of other similar rounds in the States etc, they all seem to have these issues, which I suspect is inherent to these loads.
 
I've fired similar ammo from 1900 and it was surprisingly reliable and accurate. Try pulling a bullet that has no neck crack and see how it looks. Might be you can get one show out of some of them.
