Hodgdon says you can use either the FFG or the FFFG in a .50

What are you guys using?

I use T7-3f in all of my percussion guns, even in the Knight DISC that have been converted to cap ignition. It is easier to ignite and it burns a bit cleaner. The main reason that i made the switch from 2f to 3f was temperature.... It becomes more difficult to start 2f in extreme cold - 3f on the other hands does start easier for myself.

Heredoggydoggy:
The "F's" simply designate the size of the powder granules. Has no bearing on burn rate or anything else. 3F might weigh a bit more than 2F per volume, but probably not noticeable in a black powder gun.

Dirty Mike:
because everytime i fill my measuring tube with 3f, if you barely tap it 100grns goes to 85 to 90 grns, but with 2f it doesn't do that

Might want to be a bit careful with that one... because of the size of the granuales, T7-3f burns faster, reaches higher peak pressure sooner and creates about a 10% boost in power over T7-2f. That relates to almost 25% more pressure that regular BP and/or the Pyros...

T7-2f and T7-3f will both compress down if you tap them down. I am a tapper I tap them both down. The KEY is do the process the same everytime that you do it. That maintains consistency...
