The hollow bottom has nothing to do with easier pouring but only with glass STRENGTH.
Glass is weak in bending (not many 12ins rulers about!) but strong in tension and compression.
The "cone" at the base is under compression form the pressure inside the bottle and this puts the end of the bottle (the tube part) into tension. If the base was flat, instead of cone shaped , it would 'bend' from the pressure and thus break.
For the cork capping machine to 'grab' the bottle firmly, when it is being capped. And to lessen the gas force formed by the wine when the bottle is being opened.
The concave indentation at the bottom of a wine bottle is called a punt. There is much discussion as to why they are part of the design of a wine bottle but the most realistic answer is long ago when wine bottles were hand blown, putting a punt in the bottom of the bottle ensured that the glass blower wouldn't create a convex bottom by accident, thus making the bottle unable to stand up. Also it provided more structural strength for wines bottled under pressure (champagne). People also say the punt helps channel sediment around the edges of the bottle.
Nowadays, it has become merely traditional to include a punt in a bottle design. Although you can look like a pro pouring the wine if you stick your thumb in it.
Most bottles these days are generally hollow on the bottom. It is to keep the bottles more stable when they are stacked and shipped.
It is not a marketing trick to fool you from the real volume or something. This hollow bottom thing purely helps with the stacking.
The bottle top of bottle A fits in the hollow part of bottle B, well enough to significantly decrease the chance of the bottles shifting or sliding while being stacked, or from rolling should they be stacked sideways.

PUNT is the name of the indentation found in the bottom of most wine bottles.
The indentation at the bottom of a wine bottle, the punt, strengthens it.
If you mean the "dent" in the bottom, it's called a punt.
The indentation strengthens the bottle.
The punt is the indentation in the bottom of the bottle. When a wine has sediment in it you slowly pour the wine into a decanter and then throw out the last couple of ounces that have the sediment in them. The punt reduces the amount of wine as it displaces volume at the bottom of the bottle.
i assume you mean wine bottles. and it stops them from smashing as easily when theya re put down
Six bottles of wine are a half case.
Wine bottles have labels for a variety of reasons. They tell consumers what type of wine it is (red or white), the name of the wine, where and when the wine was bottled.
Tradition largely determines wine bottle shape.
do you sell empty 5 liter wine bottles?
The indentation in the bottom of the bottle is the puntIt helps the bottle to hold the high pressure of sparkling wine/champagne. It accommodates the pourer's thumb for stability and ease of pouring. Some wine waiters use the punt to hold the bottle with their thumb in the punt when pouring wine.

There are several filling machines specifically designed for wine bottles. Since wine bottles have narrow opening the machines must be specialize to fill them.
if you fish you can use them as bobbers and for playing games
