Kesell Centrifuge Tubes Round Bottom Screw Cap Plastic Test Tube Vials 10ml with Graduation and Writing Area, Pack of 20

Holds 100 grains of powder for my muzzleloader perfectly..with room for more if needed. Go out to the range with pre-measured powder charges once you know the best powder charge for your load.

Im using these as speed loaders for my muzzleloaders and they are perfect. The screw in lids are water tight… keeps my powder dry. They are just the right size too

Used for quick loads for muzzleloader works great

As expected

Used for black powder storage. Work great

Wifey's been storing my specimens in the freezer and the caps on these suckers tend to pop off once my semen freezes in the tube.

Perfect they seal tight the powder comes out easy to pour down the barrel. I preload them all with 105 grains on my reloading bench.

Use these for muzzleloader powder tubes while hunting , cheaper and more durable than the blackhorn tubes
