I like loose powder not only for the ability to tailor the load to the rifle, but because I'm a tightwad. I can't remember the exact savings, but between the loose powder/pellets, it was something around 2000 extra grains of powder for 5 bucks less money(pyrodex). That being said, I use T7 powder right now, not because I like it more, but that is what I have to use up. It recoils a bit sharper than pyrodex, and makes the breech plug tougher to remove. I will most likely switch back to Pyrodex when this pound of T7 is used up. Even though Triple seven says that you can clean it with water, it still is hydroscopic, and will corrode/rust the barrel like all the other types of powder. Honestly Daniel, I don't know what the current combo packs are shipped with. I had one of the shotgun/muzzleloader combos from about 5 years ago, and it came with the 100gr. limit barrel(but that was all they made then). Truthfully, I wouldn't let the 100 or 150gr. debate influence your decision. You already know what the traditional muzzleloader will do with 100gr. powder or less, and with the new bullets that are made now-a-days, make the muzzleloader a great deer weapon. I think the 150gr. tag is mostly just to sell the "latest/greatest" muzzleloader, 80-85gr. will get the job done to 125yds or a bit more with less wear and tear on you and the muzzleloader. Sorry about the rant. Have a good'un.
