Thanks for the inquiry mnmuzzleloader. Comparing the size of the flask to the size of a 1lb. GOEX canister, I would expect the flask to hold at least 1/2 lb. of powder.
The ball bag is still available.
If you take either flask at the price shown, the price of the ball bag will be reduced to $10 because I can include it in the flat rate box along with 20 plastic vials.
