I have read many accounts in which people have stated that you must reduce the max load of 777 to 15% below what BP/Pyrodex would be. And I have read accounts that state otherwise.

Looking at Hogdgon's site it says nothing about having to reduce loads for any other reason but to match the velocity of such loads. I have asked them twice now about the safety of such, but have yet to get a reply. What say you?

And I've also read opposing threads with compression of 777. I only see that you want very light compression if loading in cartridges.

When using 3F instead of 2F (.50 cal) is there a general max load reduction? Traditions told me to reduce by 5grns with no reduction due to projectile, whereas Lyman's would have me reduce it by 20-30 grns depending on bullet weight.
