Hi, I live in Texas and shoot the same game. I use a 300 Win. mag. does it all. Try one before you buy it, it may not be your cup of tea. My son bought one it is too much for him so he uses a 7x57 to 400/500. My other son has one also but prefers a 25/06 and shoots to 400/500 yards. For Elk 25-06 would work with good bullets if the range is kept in mind.
