Indiana just changed its deer hunting equipment laws for this year and I'm trying to decide if I should make a change. For the last several years I have used a marlin 1894 in 44 mag using leverovultion rounds with good success. With the new options this year I am considering buying a 243 for deer instead. Most my shots will be under 100 yards and 125 is probably the furtherest for my location. So is the 243 much better in this scenario? Is it worth going and buying a new rifle?
