Hi all, my first post in this section, & silly question #1!!
Just bought a Pietta New Model Army; .44, colour case hardened frame & beautiful!!
After borrowing a BP at my club, loading & shooting 18 shots, I was hooked! Went straight to a gun shop & fell in love, & bought the above.
Now two questions I need answered quickly before I can go & break her in (gently )
FIRST I asked in shop for grease to put on top of charged ball, & they were out of stock. Like a pratt I forgot to ask what sort of grease is ok to use so I could get some elsewhere. In the book it says 'crisco' or hydraulic pump or veg grease.
Tell me what to get please, no brand names as they probably won't have it over here under that name.

SECOND guy in shop, who is an ardent BP shooter, sold me some F2 powder , which I assume is FFG & in the book on reading it at home, it says use FFFG.
Is this a problem or can I just use this batch up first?
Tried to ring shop but can't get through ATM
Cheers
Dave (I'll be back!)
