T W 54 AP M2 Ammo Corrosive?

[oldfoneguy]

Gentleman just as the title asks. I have a partial bandoleer of T W 54 AP M2 that I have no idea where it came from or when I got it. This isn't something I would have purchased as I only recently bought a Garand. I found this at the very back of my ammo locker. It seems to be very clean and well stored with no round corrosion or rust on the clips.

Now where I worked I was known as a firearms enthusiast and shooter so when a guys dad or uncle or so forth would pass away I was generally gifted with whatever they had laying around after the estate was dispersed. I can only assume this is one such item.

Back to the questions at hand,
Is this ammo corrosively primed?
This is armor piercing ammo?
What manufacturer is T W?
Am I correct guessing this was made in 1954?
I assume it's Garand safe as it's id'd as M2?

Thanks in advance for any responses.

Yes, black tip is armor piercing. Headstamp is Twin Cities, https://en.wikipedia.org/wiki/Twin_C...munition_Plant . Yes, year of manufacture is 1954. As I understand it, the greatest amount of rifle ammo issued for the M1 rifles in Korean conflict was AP. They discovered it carried better to target and was more accurate.

Thank you Tom and Jim. I'll try this stuff out to see how it does next range trip.
