BH209 seems like it's the way to go for loose powder. That said, I haven't switched to it yet as my muzzle loader can't shoot it.

I like the pellets more than most guys on here because when hunting I find them a lot easier to handle that loose powder. That said, I also have some loose powder I use sometimes at the range. My current muzzle loader shoots the pellets and the powder to the exact same POI and it acts exactly the same. So I use the loose powder at the range to save money, and pellets in the field.

However, the Genesis I used to have loved the Pyrodex pellets, but I tried T7 pellets and the groups opened up. Being that it shot better with Pyrodex, and Pyrodex was cheaper I stuck with it. I then later tried the loose powder in it, and the groups opened up to huge groups. I thought something had gone wrong with the gun. I was literally getting 4" groups with 100 grains of loose Pyrodex. I switched back to pellets and it went back to shooting it's normal 1" groups. I'm not sure what the deal with that gun was, but it hated loose powder and loved pellets, so that's what I used in it.

So as you can see I like both, but you really need see which one your gun likes.
