120mm M103 Heavy tank ammo

[917601]

Posting pics of a 120mm AP round. This one blue, a practice gunnery round. A massive round, 52” tall. It was seperate loading, tank gunner inserted the projectile into breech, then the massive brass casing. The 120mm gun originated as a 50,000ft plus AA gun, in the late 50’s designed it into the M103 Heavy tank. The Marines finally ditched the massive M103 tank in the late 70’s.

In AAA terms, that’s the Stratosphere Gun.

A pic to realize the size. IBM ( itty bitty marine) is handling an HE round.

Another pic for size comparison. My Black 120mm AP ( same as my blue practice round, but has a hardened steel bolt) pictured next to a modern era 120mm kinetic AP. 50’s tech vs 2000 tech. 2700 FPS vs 5,000 FPS.

I thought the 155mm howitzer rounds I have were big !

Hate to be the poor SOB stuffing the breech, they all must have had arms like tree trunks.

Have just the projectile of the 120mm . Let's say it is something not to stub your toe against as I did one night.
