I usually have a couple different rifles in the stand with me. If all the hogs that come out are small I will usually use my 204 Ruger and I always take ears shots. I haven't had one take a step with the biggest being about 100 pounds. If I have bigger pigs out I use my 270 and I try to take a shoulder shots and line up another pigs head for the exit. I ended up killing three doubles and one triple last year. Its not real hard here in Texas when you have 20 or 30 coming out at a time.
I got a new 50 cal muzzle loader at the end of the season last year and have been mainly hunting with that and having alot of fun. I have killed a couple hogs but have only taken shoulder shots but since it is so accurate I do believe I will put a few in the ear hole.
