RE: 30-30 for deer
Simply stated, it is an adequate deer round in the hands of an experienced hunting rifle shot...out to 125-140 yards. It is no more or less than that...IMO. In the fastest loadings of the 170 grain ball, it is quite lethal within ints limitations. It is no wonder round, despite the # of deer that have been taken with it.
It quickly becomes a liability beyond 150 yards.
