Its an American company and they tend to stick all sorts of restrictions on their products to avoid law suits.

The dont use a flask warning is mostly relevent to single shot, fire it reload it and the risk of a glowing ember.

That said my club demand use of vials so you can see the measures all look good, we had one guy short measured from a flask and the ball bounced back and hit another firer.

Stick to vials, we like safe shooting.
