I loaded up those 130 SST in .270 Win the last couple years for deer. shooting that 2nd last one from the front/side, the bullet went in, took out a rib, cut the heart off at the top, liquified the liver, took out a/the lung(s), took out another rib on the other side and kept going. I don't know if there's a point in going down to 130 grains though. Why not 140s? The SSTs went right through a fat doe, straight front to back the year before too. Through and through, while still exploding and doing some nasty damage inside.
