i have decided to change from pyrodex powder to 777 powder, i now use 80 grains of pyrodex. if i use 80 grains of 777 how will my bullet impact change?, i don't want to use too many shots as powder and bullets are getting higher all the time. i now have my optima shooting dead on at 100 yds with pyrodex, i checked with hodgen and they reccomend dropping the charge down to 65 with 777 to make bullet impact the same. i would like to know from ya'll that have made the switch to 777 and how ya'll did, it seems 65 is a little light and besides my measure only goes in 10 grain increasements so i could drop to 70 if thats true. thanks for any help.
Try 70 grains of 777 powder and you should be real close. The difference is 10-15% difference. Be sure to check it at the range. Personally I like Pyrodex RS powder better then Triple Seven. I'd rather spend five additional minutes and shoot Pyrodex RS. Also when shooting 777 pay attention to crud rings. 777 likes to form a hard crud ring just above the breech plug. Swabbing will take care of that. Granted Pyrodex RS has a crud ring, but it is much softer.
