I get excellent results with both the shock waves and the xtps. I use the 300 gr in both. But the SWs in 300 gr are getting hard to come by. And I throw away the sabots that come with the SWs and use Harvester black cursh rib sabots. These are more consistant in the pressure required to load them, unlike the sabots that come with the SWs. As for the XTPs, I use the .44 cal and the Harvester green crush rib sabots. The XTPs are devastating on game.
