Chalk rounds? They were like throwing marshmallows but still very accurate.
We fired M433 rounds, the stubby, gold-nosed cartridges. Luckily I only fired 3 or 4 rounds cuz my shoulder was sore for days. I figured they gave us Apache rounds. Those things were heavy.
I always used the quad sight cuz the leaf sight was crap. Using the quad sight the 203 was very accurate. I remember we were firing at old M60 tanks on the range at WildChicken. My MLRS TC was the range NCO. Seeing how accurate the sight was I used my last round and aimed for the CDR’s hatch on an M60 about 100+ yards away. Aimed for the hatch’s lip which was about 2” high. Hit it. Boom! I yelled with joy. My TC turned around and gave me a sickened look. “Yeah, that’d be your hatch SGT” was understood.
I loved being in the Army in the ‘90s. Too bad I got injured. At least I was finally awarded my 100% after 25 years.
