If your gun has a Patent Breech. (yours most likely does) Your touch hole will swallow around 3 pans worth of 4ffff powder.
Best solution is to just use 3fff powder, as your primer, when you are hunting or trekking.... the 4ffff might be a little faster, but not if it is all gone and your pan is empty when you go to shoot
Save it for the range or tree stand.
Look around this sight and watch the vids, You will see a LOT of the Myths and theories put to rest, as being "Just Not true".
