depends on the shot...usually one to two

It depends on the shot glass. This is why drink recipes call for ounces and not shots. Most shot glasses are either 1 ounce or 2.

A shot is either 25 ml or 35 ml.
"The Imperial fluid ounce is...28.4130625 millilitres...
The U.S. fluid ounce is...29.5735295625 milliliters."

Imperial:
25 ml = 25/28.4130625 ~= 0.88 fl oz
35 ml = 35/28.4130625 ~= 1.23 fl oz

US:
25ml = 25/29.5735295625 ~= 0.85 fl oz
35ml = 35/29.5735295625 ~= 1.18 fl oz

Depends how big a hole the bullet makes as how much liquid the hold holds. LOL

An ounce or a little over..unless you order a double shot..:)

one is a real shot is what they taught us in bar tending class here in AK.
