General Tactics

Under 'Equipment', if you search there are a few ranges listed.

For instance:

The maximum firing range for ½ pood unicorn was 2300 m, and for ¼ pood - 1500 m.

A 'pood' is an old Russian unit of measurement equivalent to 16.4kg or 36 pounds.

A 'Unicorn' was a Russian artillery piece which was essentially halfway between a howitzer and a regular cannon. While apparently regarded as superior to howitzers, they were pretty unique to the Russian army.

Some searching in the other artillery sections should find some sources for ranges as well.

Of course, this is mostly intended as a resource for Napoleonic-era stuff, but given that the idea of a 'bronze/iron tube' doesn't change that much until rifling and breech loading become common, the information should still be relevant.

EDIT:

Ah-HAH!
