300gr thor hammer for cow moose

[mitchparker6]

I drew a colorado cow moose muzzleloader tag. I have a knight disc extreme with the 209 primer setup and blackhorn 209 powder. I've had the muzzleloader for 4-5 years now and have never shot anything with it. I got the sizing pack of thor bullets and properly sized the bullet I needed .501 300 gr hammer. Do you guys think this bullet would be sufficient enough to take out a cow moose? I already have a 50 pack of bullets bought. Other option i was thinking about was going the no excuses 460gr route. What do you guys think?
