One powder

[roundball]

The fastest ffg or fffg time was slower than the slowest Swiss NullB time.

The variation in the priming grades was quite a bit better than in ffg and fffg powders.

I personally like ffffg, especially Swiss NullB. All recent timing that I have done is with NullB. However, in high humidity hunting situations a person may do better with a larger grade.

Or...you can just refresh the 4F prime frequently.
I refresh mine avery 30-45 minutes, period...I don't try to change the time frequency based on how humid it may or may not be...every 30-45 minutes by my watch I just open the frizzen, flick it out, brush the pan & vent opening, and reprime...takes 30 seconds and only costs a penny...every hunting shot I've ever had with 4F prime was no different than using 4F at the range

You can prime with the same powder you charge with. I prime with FFF and with the fines I screened out of FFF. The fines are probably finer than FFFF but they both work fine and I can't see an advantage of one over the other. It's just easier not buying seperate priming powder. I think they only reason they sell priming powder, is to have a way to get rid of the finer granules created during manufacture.

I think it's probably because there is a market for it. Otherwise, it would get sent back through the hopper.

When the differents in ignition time are measured in hundredths or thousands of a second, moisture does play a part in what happens in the field when hunting. I have had FFFFg priming powder fizzle, before igniting, and give me a " hang-fire " ignition when firing at a deer, after sitting for several hours before daylight in a treestand. I have found much more reliable ignition, and more consistency in ignition, using both FFFg and FFg powders for priming, instead. To each his own.

Thanks for the numbers, Larry. :hatsoff:
