ramplord you mention pergut S5 ? do you know if there is a difference between pergut S5 and pergut S20?. I also have looked on ebay and didnt find any 25 kg of sulphur.. 

Pfieuw, didn't know, works fine with me

And looking on ebay isn't the way do do it. Use google, search on 'chemical supllier' or something like that and look for big distrubuting companies.

I don't know if it's okay to post links, if it's so, I will post some

You can look at the stores where they sell custom bullet layers, you can find all sizes for a cheap price.

Sometimes it's nicer to have cilindric media, you can make it yourself by putting some lead in cutted cupper tube, of cut of some pieces of a masif tube.

I've not much experience with Bariumnitrate, but when I use it I just avoid most contact and wash my hands after it. I think you can find nice datasheets about it all over the net, they can tell you wich grade of toxicity it has. And 98% will do great for Pyro.

I recently organised an action of buying in a large amount of Pergut S5, and sell it over to a couple of people on the Dutch forum I'm in. The datasheets of it tells that it's still good after a couple years, when on a dry place and in dark. Since I just got it I can't tell you if it's still doing great after a year...
(I btw have some kilo's left, so if you're interested.. PM)

And for sulphur you should look at the internetshops wich sells it from 25 kilo. In that amounts it cost just a couple of euro's per kilo, and it's allmost allways more than 98% pure.

My apoligies for the grammar etc, I'm still a Dutchmen
