Did the British 6 pounder or the US 57mm M1 Anti-tank gun come with High Explosive ammunition. If so, when was it introduced?

They had HE (High-explosive)and WP (White Phosperous rounds) (Spelling?) If im not mistaken, they also has a cannister or grapeshot type round also.

I have a question! wouldnt grapeshot and cannister be just schrapnel rounds?

Thank you.
Do you have any idea when these rounds were developed or when they were issued.

Secondly, did the US army use the same round ( I know they were the same calibre) but were they the same?

Quite welcome. Im not sure when certain types of rounds were developed but H.E. had been around for many years. I am not certain when the W.P. rounds came to being. I guess you could say that in a sense, H.E. rounds were grapeshor or cannister even though they were not filled with tiny balls but the schrapnel came from the shell casing when exploding or as on Pinapple handgrenades and made as such a way that more debris is created when the shell or grende casing explodes.

The US Army used these rounds and I suppose they still do. I will try to ask a friend of mine who is a Captain in the army for more on this as soon as I can. This friend was a Company Commander in an Artillery unit but is now with an Armored unit. I will let you know when I find out. Believe it or not, they even had an artillery piece that fired Nuclear artillery shells.

The Germans had a "pinapple" type grenade also. A type for the stickgrenade even had a separate "pinapple" sleeve that could be slipped over the existing stickgrenades sleeve to produce more schrapnel.

Maybe 6pounder HE had been around for years, the WW1 6pounder (57mm L23 M1916) gun fired only APHE but by Dieppe (August 1942) the new 6pounder tank guns had only AP/Tracer ammo and HE ammo was not yet available.

6pounder tank guns fired HE ammo later in the war and presumably this ammo 'fit' the anti-tank guns of the same calibre.

But were the ATG's issued with HE ammo?

I don't know but, I will ask a friend of mine who is a Captain in the US Army and used to be an Artillery unit Co, and whenever he does get back to me, I will post it here. It might be weeks or months before that happens.
