I know loose 777 is ~15% hotter than equivalent BP or Pyrodex loads, but I thought I had heard 777 pellets didn' t have much if any velocity benefits over Pyrodex pellets. Is this correct? And if loose 777 is 15% hotter, why couldn' t you use 120 grain 777 loads in place of 150 grain BP magnum loads, or is that 100 grain restriction just for pellets because they only come in 50 grains. That would be decreasing the load by 20%, so you should still be within comparable pressures or am I getting confused. That happens from time to time.
