Monocapa prime comp adjustment

[fieldworker]

Hey folks, I dont have access to Kperchlorate or chlorates as it is banned in our country and Im not even planning to make some with electrolysis, so i have Knitrate,Banitrate,Srnitrate as oxidisers in my hand. Thats why i want to change or adjust the monocapa prime mix with the selected oxidisers that I have in my hand. Apart from that black iron oxide is also very hard to find here. So what should I use in place of Kperchlorate and black iron oxide, Im planning to replace Kperchlorate with Banitrate(not sure about the amount suggestions will be much appreciated) and what I should use in place of black iron oxide. Thanks

 

Monocapa prime comp:

 

24.6 Potassium perchlorate

31.1 Potassium nitrate

11.5 Charcoal (air float, Willow or Paulownia)

4.1 Red gum

4.9 Sulfur

7.4 Iron Oxide (Black)

12.3 Magnalium (230 mesh, or dark aluminium)

4.1 Dextrin

My suggestion is to try Fence Post prime instead.

Optional after priming is to roll/shake the stars in some hand sieved BP.

You can also use a meal + silicon prime. 10-15% silicon would ignite reliably about any composition.

Well i just wanted to know that if I replace perchlorate with barium nitrate will it work?

Subbing 25% of a comp is going to change it's performance. Do a lot of tests at a safe distance and tell us all how big that change is.

I don't think this would work.

The formula is developed with perchlorate.

 

Also barium nitrate is a much more sluggish oxidiser.

 

If you have no perchlorate, you have to develop a new formula. Or just use meal + metals, as posted above.

Use step priming.

ok thanks for the suggestions I will try once with barium nitrate and will post the results and comp here, I have also other things planned so it may take some time.

As a_bab said, BP + Si will ignite almost everything. Even when it is broken pretty hard !
