In-Line Ignition?

[Swamp Fox]

I have a Traditions .50 in-line and I've been using Pyrodex in it. However, I'm thinking of switching to Blackhorn 209.

My question is: Will the fire from a #11 percussion cap be enough to ignite a 90 grain load of Blackhorn?

Thanks

No, Blackhorn is made for sealed 209 ignition systems
