RE: 777 pellet equiv to Pyrodex RS (grams)
Good point bigcountry. If you're going to use loose Pyrodex RS just load 100 grains of the loose and it should do the same thing as two pellets of the Triple Se7en you were using.
Now a days I shoot all most all Goex. The crud ring problems are not as serious. Granted they still exhist, but a wet swab will take them right out of the breech and bore. Goex also seems to really be constant unlike some of the other powders. I have one rifle that loves Triple Se7en so I keep a jug around for it. And one little .50 caliber really liked Pyrodex RS for accuracy. The rest get Goex FFg & FFFg.
