I would like to get as much info on this ammo as I can. I purchased it several years ago. The brass is berdan primed and shoots about 2400fps from our G.24(t). In particular I would like to know the following

1. Ballistic Coefficient of this round
2. Although I measured this pulled bullet to 196.8gr and I know the bullets would vary, I would like to know what grain this bullet was listed at.
3. The powder was square flat flakes, is this ammo corrosive. If so how do I clean my barrel now?
4. What is the jacket made of, steel?

The headstamp will help us answer your questions.

Does the case attract a magnet?

I have a picture of it in the attachment

The top has 7.92, there is a capital A on the right and left of the primer and across the bottom 1955

Yes it's corrosive. Clean it the same as any other round, just do it after every shooting trip, i.e. don't let it sit for days after shooting.

Pour hot water down the bore since it is corrosive, dry the gun, and then clean like normal.

It is made in Ecuador, it is corrosive. The powder is not the component that is corrosive, it is the primer. It is a 196gr. FMJ bullet, if it will attract a magnet, it has a steel core.

Just because a magnet will attract to the bullet doesn't mean it has a steel core. It could just be the jacket of the bullet.

Oh, I just happened on this and had to go pull a box of it out of my ammo cache... :evil:

Yeah, made in Ecuador, and the primers are corrosive.

The bullets are called 196 grains by those of us in North America, but since the Germans have been metric forever, I'm sure they call it something else in grams anyway. For all intents and purposes, it's 196 grains.

The 'SS' on the box does not mean "SchuetzStaffel" - the SS you guys think of dudes wearing black uniforms. :scrutiny: "SS" in this context is "Schweres Spitzgeschoss." This is Heavy Pointed Bullet" were the Spitz is the same root as Spitzer.

My ammo pulls a magnet HARD, so I'm guessing it's steel core. The jacket may or may not be steel, but since it pulls so hard, I'd say at the core is steel.

This ammo shoots WAY better in my M98k than any other MilSurp ammo. Of course, it kicks harder since it's heavier than the lighter (what, 154 grain?) common surplus.

So...WHERE did you get this stuff? :confused: I bought a supply years ago, and I'm down to a small pile. I'd love to get more of this. So - Please - could somebody post or drop me a note where this stuff is available? Thanks!

Hope this helps. I don't know about the BC, but this ammo was commonly used in machineguns (MG34, MG42) where the longer range of the heavier bullet was a big deal and the recoil was no problem.

WRONG!

The component in corrosive primers is a salt. You MUST use water, better hot soapy water, to dissolve those salts.

Our military has some cleaning solvent that was available during WW-2. It came in little green cans. It smells terrible, BUT it works to completely nuetralize those salts. Most gun shows will have somebody selling it, buy some for your surplus ammo. Or flood that barrel with plenty of hot soapy water, rinse with boiling water, the barrel will be dry when it cools. Then clean with smokless powder solvent and brusses/patches as normal. Leave a filmof oil in there.

jjohnson,

I purchased it back in 97 or 98. It has been sitting in a green ammo can since then. For some reason I took it all off the striper clips and stored in a ammo can. I have only shot 2 rounds throughh my G.24(t) and that was this weekend. I followed these two by about 20 or so rounds of winchester and remington commercial rounds.

With that said, how much salt would have been left in my barrel after so many regular rounds?

I used Hoppes 9 last night on the barrel. The description on the back said it would clean barrels that has shot corrosive rounds. I oiled it too but may do it again tonight with warm soapy water and re-apply oil.
