Thanks for your replies guys. If I were to pick up some new propellant. Would you guys recommend pyrodex or triple seven??? powder or pellets for hunting???

If I sight my gun in with the old pyrodex (and it works fine) but then switch to a new type of powder (even though I'd keep the "grains" the same), should I be concerned about that changing the POI, as I may not get another chance to fire it until hunting season (I'll make sure I make time to fire it again or just use pyrodex powder for this year if you guys think it would change things measurably)

Thanks Again
