Just remember, as far as 777 powder goes, if you are used to shooting say 100grns. of say Pyrodex you will only want to use 85grns. of 777. Shooting 100grns. of 777 is the same as shooting 115grns. of other standard powders.

In other words, you want to reduce measured 777 by 15% compared to other standard powders.
