Yep, that will work.
I'm shooting a muzzleloader now, and i'm trying the 460 gr No Excuse bullets next year. It should put the hurt on them, even at slow speeds.
I broke my back, and had to skip hunting this year, but i'll be hard at it again next year. It only takes me 30 mins to get to the area in those pictures I posted. So, I always know what conditions i'll be hunting, and long shots are never needed. Makes life simple. I go up there all summer scouting with my dog. I hardly ever get lost now.
