Welcome to the board. Nice to see another Coloradean here, even if you may only be a temporary colradean.
Some of the responses you are getting are refereing to the MaxiBall and some to the Maxi Hunter. As you probably know, they are two different bullets.
In my own experience with a TC Hawken and the MaxiBall, it only took one deer and one elk to abandon it. At this time I use strictly round ball, but in a .54. If I were going after elk with one of my .50's, I'd be going to a conical again. I'm sure the .50 and rb is adequate and there are a bunch of guys on this board who have killed elk with the rb in a .50, but still, I like that extra margin of the .54. That's just my opinion though.
The MaxiBall has to much of a point to it to make a decent wound channel, IMO. Both the animals I killed with them were very slow to die.
I don't like the idea of hollow point lead slugs for big game. One of my hunting partners hit a deer head on in the neck with a HP buff bullet and a hefty charge off ff and the bullet expanded so much it did not exit. That's not very good in the penetration department :shocked2:
If I were going to load up conicals in my .50 for elk again, I'd get the Lyman .50 Great Plains mold and roll my own from it. It has a nice wide meplat and should provide a good wound channel without overexpanding and stopping short of the second lung!
Anyway, that's my .02 & 1/2 cents worth on it.
