DENNIS ANDERSON ¥ danderson@startribune.com ... 2007 .... "Black rifle'' is the name generally given to assault-style rifles. These semi-automatic guns are legal for deer and other hunting in Minnesota and Wisconsin, among other states. They differ very little from most typical "sporting'' arms. Primary differences are the design, which originated for military use, and clip size. Some black rifle clips can hold as many as 30 rounds, compared to four rounds typical of many hunting rifles.
