7. All smokeless powders deteriorate chemically as they get older. This rate of deterioration can be accelerated by such things as storage in warm conditions,exposure to other chemicals and exposure to direct sunlight. Any such deterioration may ultimately lead to a fire through spontaneous ignition of the powder. CHECK containers of smokeless powder regularly for possible deterioration through age or inadequate storage. Yearly checks are recommended wherever average daily summer temperatures exceed 30 ºC. Where average daily summer temperatures are usually below 30 ºC checks should be made every two years. CHECK containers of smokeless powder for possible chemical deterioration through age or inadequate storage. Such deterioration may ultimately lead to spontaneous ignition of the powder. Chemical deterioration of smokeless powder can be recognised by carefully smelling the contents of the container – any deterioration produces an acrid, acidic odour quite different from the normal sweet smelling odours of ethanol or ether which are usually present. Rusting of metal surfaces exposed to smokeless powder can also indicate deterioration.
Keep your powder in it's solid black plastic container and not the clear hopper of your dispenser.
Now you don't have to worry about what powder you left in the dispenser because there won't be any powder left in the dispenser.
It still would be a good idea though to have colour coded powders. I know I have a friend who has tipped a powder measure or 2 of 2213 into his 4KG 2209 bottle, luckily no harm done, but yes, I only dig one bottle out of the cabinet at a time now, as well as keep the powder type written on the ammo container and keep the lable on the bottle facing me.
It will sure keep Ken from ADI busy with his little paint brush putting a little coloured dot on each grain though.
ADI powders can be reliably distinguished by the diameter of the granules. The typical reloading bench usually includes a set of calipers. I used to have a table of powder granule sizes and tolerance ranges, provided to me by ADI. I used this information for inspection of ammunition samples taken during Queens competitions to check rules compliance.
simple sollution to it all .. dont leave powder in powder thrower , put stuff away when finished with it . as for dangerous people , all i can say is RUN FOR THE HILLS !!!!!!!!! & take up sewing or lawn bowls . now i know im going to be in trouble AGAIN .
I totally agree with that ,just remember that any changers to the power product will cost money and hit your pocket,and there are low income shooters out there that enjoy the sport also ,not only the rich.every extra dollar on a 500 grams or more,turns shooters away,so forget colour coded powder and just be bloody safe when loading.
this subject is over and i am very surpised it even came up .
