How much difference is there going to be between using one powder vs another? I've only ever shot one k ind of powder, the cheapest kind i could find. Would it benefit me to try other powders?

It all depends on what you are trying to accomplish.

You were very vague in your thread question. Never mentioned if you had a money-spending limit, what powder interests you most(real or subs), what gun ya' have, whatthe powdercosts you, using heavy or light bullets,what your bore-cleaning experience is, what consisterncy you are getting jug-to-jug, if you need a powder that works withmultiple ML styles.... etc.... etc... etc.

So that's why mysuggestion/answer doesn't exist in this reply.

There is a lot of differance. What would benifit you depends on what you want to accoplish . What did you shoot Elephant black? Lee

I started out using Pyrodex pellets, then bought a couple pounds of Triple Seven, which I liked. This past fall I found Pyrodex RS for $5/lb; so I'm going to have to like Pyrodex RS, since I've got four pounds of it. Had it to the range once; works fine. Dirtier than Triple Seven, and stinks.... but worked fine. Seem as accurate, but I suspect either powder is more consistent than I am.
