carbon steel, chrome steel, stainless steel, glass, zirconia, tungsten carbide, agate, sintered aluminium oxide, silicon carbide and hard porcelain.
Does anyone have any experience grinding Ammonium Perchlorate? Is milling needed, or would a coffee grinder get it down to a useable mesh size?

IT'S ORANGE and there was a rather strange smell. I think there might have been some reaction with the media I'm pretty sure they were chrome steel, but they seem to have tarnished... Any ideas what's going on here? I'm a little worried!

I used a new one because I was scared of contamination.
I've milled Kn03 with the same setup with no problems.
So no ideas, then?

I'm still a little concerned about my orange powder. It seems to perform well, and no further reaction has occured, but I do worry about its storage. Any ideas what I should use to replace my dead media - I don't want to ruin another load.

From a gun shop
I don't know where exactly you'd get them in the UK

This was discussed before - using Marbles for milling media is a bad idea ? not to talk about the fact that they are not nearly heavy enough.
So there are no special requirements for milling Ammonium Perchlorate? If not, I will just find the cheapest option (probably marbles)...
When looking at media you need to ask yourself a few questions:
1) Is it sparking?
2) Is it heavy enough?
3) Does it mill itself?
4) Will contamination from the media affect the chemical milled?
5) Will contamination from the media will effect the composition the chemical is in?
Of course, and answer of yes to one of the question does not necessarily mean that this media is useless. For example, sparking media can still be used to grind hard metals one their own..
Glass in general mill itself and the inclusion of glass in compositions has been proven to move the sensitive scale for certain compositions from ?not-sensitive? to ?very sensitive?.
Note that most Gun Shops in the UK sell very small media which is not suitable for milling. You need to look at ? inch balls and above, and those are not commonly used in everyday shooting. You are more likely to find such media in shops that deal with black powder.
Also, you need to check is the media is ?virgin lead? or hardened lead. Virgin lead has not hardener added ? and might disintegrate very quickly, although this apparently depend on the manufacturer. Some gain more density in the given area and then the ball is effective as harden one. I don?t know of a research on subject, this is just from personal experience.

I'm still a little confused about my metal media. The balls all appeared the same - shiny and reflective, yet most of them were destroyed by the AP. I just need to work out what the few that survived were made from. Can anyone to tell me the difference between Chrome, Carbon, and stainless steel in regard to milling/chemical compatibility?
