I have a Handi 45/70 that I bought in the spring.I have since seen the need to add other barrels.My wife has given the sign of approval for 2 more when hunting season is over.My question is,which calibers should I get and why?I hunt deer in SW Miss primarily.The area I hunt in consists of hardwood,pine and some cutover/open fields.I own a few deer rifles already(300 WSM,270,7mm-08,50 cal ML,and 45/70).Its hard to decide what I want and input would be appreciated.Dont "need" anything but I just feel the urge.Im sure lots of you know the feeling.
