Hi There Erich,
Welcome to the forum!
I took a look at the Cabela's web page, and it looks to me like the rifle (or carbine) that you are talking about would work well for Texas deer and/or hogs.
A few things I noticed that you might want to consider:
1. The twist rate of the barrels is 1 in 48", meaning they would probably shoot best with the patched round balls (as is offerd in the "kit" version). This is in keeping with the "Traditional" muzzleloading scheme of using round lead balls rather than the newer plastic sabots with different kinds of bullets. Thsy usually shoot best from barrels with faster twists, like 1 to 28", or so.
2. These appear to be available in either percussion or flintlock versions. If you want to go with the flintlock version, it is a bit MORE traditional, and there are lots of guys on this forum who like to use nothing but flintolcks, or even older types of weapons. You could get a lot of into from them, too.
3. The brass stuff really isn't hard to take care of. I have a hwaken that I bought in the 1970's, and it is easier to keep the brass (if that's what it truly is) clean than it is the blued barrel.
4. As I understand it, this type of weapon does NOT do well with the pellets. They have a higher flash (ignition) point, and require a hotter flame than either a percussion cap or a flint gun normally produces. The manufacturers of pellets usually state that they are to be used in "inline" guns only.
5. The .50 cal is a good all-around choice, but I've seen lots of guys say something like, "if I was going to have only one gun, it would be a .54." It seems like the larger caliber will take down anything a 50 will, PLUS gives you more options if you ever want to ga after something bigger, like elk.
That's :m2c: worth - hope it provides you with some initial information.
