I have a T/C contender super 14 in 45-70 caliber. I am planning on getting another barrel to use for javalina, (a collared peccary, adult weight 35-60 pounds). I was considering 223, 7-30 waters, or 30-30. I have not been able to find a comparison of theses calibers, and would welcome any information and/or advice on these choices. Thanks, pj
