I have been using Pyrodex RS, T7 loose, and T7 pellets. I like Pyrodex RS the best. I can't see where T7 is any easier to clean than Pyrodex, if anything it is harder because it leaves a worse build up in my opinion. And no matter what you still have to go through all the same cleaning steps using either. The only advantage I have found using T7 pellets is that it is faster/easier to reload, and it is easier to unload by removing the breech plug after hunting so you don't have to fire the round or leave it loaded.
