I have never shot a deer with 100 gr Interlocks or Spire Points, but my late friend who sold me my .257 Roberts killed a dump truck load of deer with them evidenced by the many racks in his house and garage. No telling how many does he killed either. His handloads with H380 were accurate, as well. I shot about 50 of them at target practice. I’ve got 3 boxes of them that came with the rifle, but shoot 100 gr Barnes TTSX these days. Good hunting!
