I have almost a full lb of 4320 left over from the 1990s. I would love to have some 6 ARC or Grendel data for it. Seems like it's right between TAC and CFE 223.
Give the 70 grain Speers a try. Definitely not a long range bullet but inside 200 yds I have had good luck with them on hogs. They are accurate, cheap and typically easy to find. I have only shot one deer with them and it was a white patch shot from about 75 yds but I would not hesitate to...
