In my opinion, a .25-06 would be a great caliber for use on both of those animals. You can get out there a little bit with it and it packs enough punch for both. Your muzzleloader would do the trick, but you only have one shot and I would want something that shoots a little flatter for a possibly long range antelope shot.

Take a look at what I think is an often overlooked caliber, the 7mm-08.

Unit 5A, I think we may have been a little late on our posts.

dms-13, what did you go with and how did it turn out?

Well, there are always a couple of guys trying to catch up. Look at us!
