Better...Two of my inline buddies used 777 one year, ended up bringing them to me to fix...I had to lap the bores with JB bore paste to get the bores smoothed out again...That crud ring can be tough on some guns, why put up with it???

Another factor, Pyrodex came out in the 70s...It was developed with a higher ignition temperature so you didn't have stringent shipping regulations and didn't have to store in a fire proof safe...It was not developed to be easier to clean, that came later when Marketing got involved...

Since real black powder ignites at a lower temperature in some guns it gives more consistant ignition...

This makes Goex "better"...
