My hunting buddy and I both use the .429 Hornady XTPS...He uses the 240, I use the 300...His gun likes 85grs 777, I use 80grs Goex FFF...We both use the Harvester plain green sabots...

We both kill deer, very little difference...I may get a few more pass throughs but it really doesn't matter as they don't go far...I'd say 75% drop within sight...
