Hi, folks,
To some extent this thread leads on from the 777 Advice one, because I've used 70 grains volumetric of 777 FFG behind a 535 grain Custom Bullets Minie in .577 Snider. Any airgap was filled with Trex. I've also tried thin wads, thick wads, and reduced loads with the resulting airgap filled with polenta - because no bugger else in the family would eat the stuff .

I think this load was perfectly safe to shoot, and it didn't have the severity of Pyrodex, which at one time was causing the middle band of my 3-band to shog forward and pulling the ramrod out as well.

But it wasn't at all accurate, and I think the heavyweight Minie in the 78" twist was the problem - Gawd knows I've tried changing everything else. Do any of you good gentlemen know where I can get either .600" round ball, or a shorter bullet closer to the original 480 grains? I'd rather avoid casting.

Regards,
MikB
