Forgot to mention.
You may start seeing adds and Internet discussion on yet another version of the Black Mag powder. This one is Black Mag XP. I looked for it last week at Cabela's but they did not stock it.
Price is $29.95 for a plastic container holding 10 ounces of powder.
The claim that was made to a cowboy action shooter I know was that you can reduce your charge by 1/2 when using this powder. Using half the charge you would normally use with black powder will produce the same velocity.
When pushed it was stated that this powder does contain potassium perchlorate. Two years ago I had looked at the patent covering the Black Mag 3 powder. Contains a healthy slug of perchlorate.
For those with an industrial chemistry background. The description of the production process where they co-precipitate potassium nitrate and potassium perchlorate is a riot. Almost describing it as a new chemical compound.
It was also stated that this powder, and its combustion residue, is not corrosive in the gun or in fired brass in cartridge applications. This one I must see!! a non-corrosive perchlorate???

Bill,
You were right as usual. I just received the Feb MB and found an article on BMI’s priming powder called “Flash”. The writer said the ignition was instantaneous but also said he hadn’t fired a flintlock in years. No actual timing was done.
In looking over the web site I found no data on Flash. The specs sheet says their new powder has a lower ignition temp, but doesn’t say what the temp is.
I sent an email to them this evening, hoping for a sample to time. Only “time” will tell.

Pletch
