From my understanding 777 pellets are not just 50gr of 777 loose pelletized? Right? 3 777 50gr pellets are supposed to build the same pressure as 3 pyrodex pellets? Is this correct? So is 3-777 pellets the same as 130gr of loose 777 ffg? Has anyone tried comparing velocities?

Thanks for all who respond.

Also, does anyone think that 777 is much less corrosive than pyrodex or Goex? Is is alot more corrosive than smokeless?
