Flame temperature and gas production of percussion caps

[Naphtali]

The following data were published in:

Muzzle Blasts, Ralph Lermayer, "Madison Avenue, Congress, and Controversial Ballistics," May 1998, page 42.

• 
  CCI Primer And Percussion Cap Chart
• #200 Lg Rifle . . . Flame Temperature F° 3024 . . . Gas Volume (cc) 11.68
• #250 Lg Rifle Mag . . . Flame Temperature F° 3717 . . . Gas Volume (cc) 11.97
• #209 . . . Flame Temperature F° 3024 . . . Gas Volume (cc) 21.98
• #10 . . . Flame Temperature F° 3024 . . . Gas Volume (cc) 6.53
• #11 . . . Flame Temperature F° 3024 . . . Gas Volume (cc) 6.53
• #11 Mag . . . Flame Temperature F° 3024 . . . Gas Volume (cc) 7.59
• Musket Cap . . . Flame Temperature F° 3717 . . . Gas Volume (cc) 14.36

Please note that these data for musket caps identified before CCI made changes to "re-enactor's" musket caps.

While I cannot confirm that other cap manufacturers' products offer the same numbers, it is likely that percussion cap data are very close among them.

Hope this information is useful.

Good info. Thanks for posting. Do they have information on flint lock frizzen scraped material and temperatures too?

The white hot, bursting sparks off of the frizzen are about 3000 degrees F.
