You’d be surprised how much metallurgy advanced. Western shells from 50s and from 90s are completely different beasts, but difference is less in NK ammo, which means lower range and lethality out of comparable calibre. This way NK 180mm shell is less lethal and maybe shorter ranged than western 155mm, it’s closer to modern 105mm
A simple explosive shell from the 50s and one made today are not that different. It gets launched and goes boom, doesn’t take a genius to manufacture
