I have just bought a Parker Hale 3 band Enfield .577 and was thinking of using 777 as I have a good supply of this powder (I use it in my Ruger Old Army). The powder I have is FFFG.
Can anyone tell me if this is okay for the 577. The previous owner used 50gn of Swiss for shooting 100 metres so I thought 40 gn (all by weight) of 777 would be about right. My club range is only 50 metres. Or, should I be buying something like Pyrodex? I have no black powder licence so a propellant is preferable. I am a complete beginner with a muzzle loading rifle so deadly accuracy isn't a consideration.
Any help or advice would be much appreciated.
