T W 54 AP M2 Ammo Corrosive?

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.

No - n/c after 2-52 at TW.
Yes, black tip is AP.
Twin Cities Army Ordnance Plant, MN.
Yes.
Yes... IMHO.

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. Here's a thread from CMP reference your question about corrosive primers from TW. Armor Piercing Ammunition from CMP [Archive] - CMP Forums

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