I thought I would get this started as I like single shots. There are two kinds of single shots, those I would like to have and cannot afford and those I can afford. Through the years I have played with several of the New England Arms break opens and have good luck with them. One I still keep is a 1871 Buffalo model in 45-70 with a 30 inch barrel. The last one I looked at was a 30-30 model that I thought would make a good plinker and companion to carry on my 4-wheeler when I cut wood. They are tough as rocks. Likely would be great for jacketed but I swear it had the micro-groove rifling. As Marlin now owns this company I assume it is a Marlin barreling system. While micro-groove rifling may not be all that bad I know some that would rather not use it for cast. Just thought I would mention that.
