My poimnt was that:
150 gr triple 7 loads do recoil ALOT for a muzleloader, I shot his rifle, and though I'm not very sensitive to recoil, it felt a lot like a 12 guage shotload that I was shooting. Shooting a dozen of these off a bench will cause people to flinch unconsciously.
I could shoot my RB rifle all day without it even coming close to bothering me.

The cleanupup of triple 7 sounds like a marketing ploy to me. You still need hot water to clean it up, and need solvents and a brush to remove sabot fouling. I think new shooters are being sold on a falsehood that the new improved muzzleloading is easier to clean up. Ask anyone who has never shot real blackpowder as to why they won't try it, the typical response is that they don't want to do the blackpowder cleanup.
