According to the Lyman Black Powder Handbook & Loading Manual, that method of measuring black powder is not recommended and could result in a very heavy powder charge. If use with a black powder substitute, I would assume one could end up with a very nasty proof load or worst.

it would be worse especially with 777
Why ? Are they measured differently , if using an incremental measure ?( 50grn bp not the same as 50grn 777)?
I have never played with 777 ,or any other sub.

777 is really a smokeless by volume sub for BP what im talking about is the head measuring posted before in this forum with pyrodex or 777 you have a pipe bomb if not measured right
Gotcha.
As an aside , I just finished measuring the amount of powder 'the old rule of thumb' gave.
To cover a .50 cal ball , on flat surface , it measured over 170 grns of 2F.
That would be somewhat of a shock I'm sure. Like I said , it was an old saying , perhaps used waaay back with poor powder and loose balls !

about 70gr of that real bp will get blown out the barrel
