Congratulations on the successful culmination of 3-years of research. Would like to converse with you more regarding that handload. I liike 170 gr. bullets in 30-30 caliber for hogs; little short range carbines that are quick and accurate, massive energy transfer, large exit hole, typically anchors them (depending on shot placement). I also have a Marlin Model 336. It doesn't like me and that feeling is mutual but my kids love it and it loves them. These are discussions for the Handloading and Marlin Boards on 'GB'Outdoors. Bon Appetite'.
