Hodgdon Reference Data for Loading Triple 7 777 and Pyrodex
The 777 loads had more felt recoil but I didnt notice any more speed due to the less powder Neither the 777 nor Pyrodex hurt like GOEX I had EASILY 45gr of GOEX in there and it was more of a crack than anything else Personally Id rather shoot Pyrodex or 777 in the Spencer until I can figure out why the heck the GOEX loads are so
WARNING Never allow an air space in any cartridge loaded with Pyrodex The loading density must be 100 by light compression 100 loading density may be accomplished in two ways The case is filled with powder to a level that will provide light compression of the powder 116 to 18 when the bullet is seated
A few years ago I combined several powder burn rate charts The Excel spreadsheet ranks the powders within each list from 0 fastest to 100 slowest When the same powder is found in at least 3 lists it averages the ranking to produce an aggregate list In general there wasnt much difference but some powders moved up or down a little

Load density must be 100 by light compression No problem Loaders can accomplish 100 load density in either one of two ways 1 Fill the case with powder to a level that provides light compression of the powder 116 to 18 when the bullet is seated Similarly bottle necked cases must be loaded in the same manner 2

For the Super Companion Owners What Powder Do You Use If 777 what
777 loose powder is not hard to ignite ANYONE who has ever shot it out of 11 guns can tell you that 777 pellets on the other hand can be harder to ignite My NEF will not give 100 reliable instant ignition using the primer carriers and 777 pellets and I wont hunt with that
With 777 you use very little compression and leave no air space between the ball and powder You seat the bullet to where it just touches the powder You will get no consistency between shots if you compress it very much 777 is hotter than black powder and you should reduce your charge by 15 of recommended black powder charge
