To an extent. But weapon specifications often have pretty gigantic error bars on them.
After all, the range of a tank gun isn't just a question of how far it can send a shell - it's also a question of how well the gun can be aimed, how hard the shells have to hit when they arrive, and whether the 'effective' in 'effective range' means a 20% chance of a kill or a 90% chance.
By messing around with those definitions, the M1 Abrams tank has a range of anything from 2,500m to 4000m to 8000m. Pretty hard to sanity-check such a wide range of figures.
