Re: Hodgdon Triple 7 granular powder

While the loading chart I remember doesn't appear to be on the site any more, you will notice the general instructions for loading 777 in cartridges. This powder was of particular interest to those of us who shoot Martini-Henrys and Sniders when it was first introduced. Some folks used far more than 55 grains. Granted the Martini action is stronger, but you certainly don't have that case capacity in a 45-70 anyway. The more technically oriented have determined that 777 pressure ramps up dramatically after a given number of grains but, again, you won't get near that in a 45-70 case. I'm not trying to push the stuff… I use American Pioneer FF in my guns, which I find has more of the boom and smoke of black. By all means use Pyrodex, It has a reputation for more consistent pressure, but you'll have to be more careful cleaning your gun afterwards. In all events, clean your brass as any BP sub will attack it.
