Pulling the trigger on a new Texan tomorrow but can’t decide which caliber

I’m going with the .457 based on feedback and everything I have read. We can hunt deer and hogs here in Alabama so the big slug option was a big influencing factor from the start. Going to add a big tank and compressor to the mix as I feel the .457 likes to consume air and slugs at a higher rate. Also looking for a mould since father in law has everything to make slugs from his black powder days. 
Thanks to everyone for the input, can’t wait to play with the new toys!
