Needed way more HCl to neutralize CaCO3 than calculated

Nevermind! Please delete this. I made a horribly embarrassing calculation error. That was all.

What was the density for? Hydrochloric Acid is a SOLUTION in water, and therefore has a concentration. For instance, if your HCl solution is 30%, 100 grams of your solution has only 30 grams of HCl.

Yeah, I was so used to working with H2SO4 where I just assumed it was 100% to make calculations easier, I somehow lapsed when it came to HCl. I definitely facepalmed when I noticed that.
