I was gifted a TC Hawken by my uncle. The Hawken is a kit muzzleloader and it has an Accra-shot nipple. I was looking for information on the temperature and velocity of the spark from a small rife powder as I intended to use T7 as my propellant.
 
Hi , ecohs from Michigan. Keep your eyes 👀 peeled for spammers or scammers. Stay aware of threads informing us regarding info about what to look for and spot them and what to do about reporting them. Thanks for your help. It's kinda like detective work. Fun and a little exciting. Steve
 
Welcome from New York State's Central-Leatherstocking region.

Don't believe I have ever seen a description of primer temperature or "spark". I have to believe it would be supersonic and somewhere below the melting point of brass (which is just above 900 degrees F).

Howdy. Just get a musket cap nipple and use musket caps, plenty hot enough. Also if you're not aware T7 is hotter than black powder so the charges should be reduced some.
 
I would ditch the Accra Shot which is a pain to use and get a good old standard #11 nipple, I like a Hot Shot. At one time I shot a lot of substitute powders, all went off just fine with a standard nipple and a #11 cap.

I didn't know that an Accra Shot took small pistol primers, the ones we used back in the day used 209 shotgun primers. We ditched them because priming a gun took so long, extracting the spent primer was a pain and added more time to the loading procedure.
 
using mag spark,, i've finally got excellent grouping with 209 primers since changing to winchester 777 209 primers.. these are 1/2 the strength of cci & federal 209 primers. they fire prb 1/2 velocity of cci & federal primers with no powder...
(i had been using rws 1075 caps).. i was getting much fouling on my malcolm scope and mounts with the caps. the mag spark cured that.. The trick for easy primer change is wetting the primer in your mouth (or with oily fingers) spit in the cap before screwing on... competitors report 60+ shots on tournament days with no problems.. & spit don't hurt 209 primer firing. photo is before mag spark install malcolm2.JPG
