Along with shooting my .58 yesterday I also had along my Marlin Guide Gun .45-70 to sight it in. I was shooting both Rem 300 gr HPs and Barnes 300 gr TSX. When I went up to bring in my target one of the Barnes bullets was lying on the bank in the loose dirt. (probably kicked up from subsequent shooting). That bullet really expanded nicely and with a moderate load too. I would not hesitate to use one on a hunt.
