Spill Proof Loading System - II

I've often thought that if a person spilled powder while loading a rifle, either gale force winds are blowing, he is loading during an earthquake, or possibly he shouldn't go in for anything more demanding than checkers. The set consists of a Warren (or Ozone Mountain Manufacturing as they came to be called) Safety First Hunting Flask. It holds 500 grains of powder and the valve has a recess cut into the tip that allows a standard 1/2" OD powder measure to be inserted into it for safe, spill proof charging. The second part of the package is an October Country standard powder measure. The measure itself is calibrated in 10 grain increments from 0-130 grains. The slide is secured with a single set screw. To load, simply fill the measure, and if you are shooting a .54 caliber or larger rifle, place the entire measure into the muzzle of the firearm and let the powder spill down the barrel. If you are shooting a .50 or smaller, set it at the muzzle and pour into from the measure. Simple and foolproof. I doubt if either item has ever been actually used. A little steel wool and Brasso and they will look like new!!
