“Do you use a different powder in your pan than in your chamber?”
-Jay Dee Fentress‎

Here are some of the most informative comments from the post.

Jim Anderson, Nope. 3f in both

Matt Fout, I usually shoot 3f in my rifle and either 2 or 3 in my Fowler. I like to prime with 4f but 3 does just fine

Daniel Lamping, In my .32 I use 3f for both. In my .62 Fowler I use 3f for charge and 4f for prime. I can use 3f for prime but it likes 4f better. Every gun is different.

Jon Wittorff, for our cannon, yes,2fa in the cartridge and 4 f in the quill

Tambi Dudley, I use Swiss null B (0B). It is the finest glazed priming powder out there. It doesn’t turn into soup in the pan. It’s faster than 3f and 4f powders

Daniel Phariss, Always. FFFF will trickle through a vent FF won't.

Mike Burton - Peter Alexander, who wrote The Gunsmith of Grenville County, said: “If your lock won’t ignite FFFg or FFg powder, the problem lies with your lock.”
