20x102 experimental projectile (proof round China Lake?)

[orpheus72]

Does anyone know anything about this projectile?

I searched the forum, and saw a thread from EODGUY ( answer #2 in this thread http://www.bocn.co.uk/vbforum/threads/73326-20x102mm-Examples) where it was mentioned as experimental proof round from China Lake.

Odd on this projectile, is that the lower tail-part is thicker than normal (see pictures), so it doesnt fit a regular sized 20x102 casing

Thanks.

Hi Geert,
This projectile configuration was designated “GP” or “GPP” (General Purpose Projectile) and developed at the Naval Weapons Center, China Lake, California. It was meant to be a multi-purpose load (armor piercing, fragmenting, fuzed) compatible with the M61A1 guns used by the three armed forces.
