I have said this before... but I see you're new.
Shooting those pelletized powders IMO is putting the cart before the horse. They are expensive too.
Personally it makes a lot more sense to me to find the bullet you want to shoot for YOUR style of hunting... then adjust your loose powder charge till you find the combination that shoots the best.
But... I know there are a lot of guys out there that go by the "More is better" school of powder thought.
