A couple days ago with my Triumph I shot 110gns BH with some 250 and 300 gn XTP's with exceptional results. Both bullets grouped under an inch at 100yds. Last night I punched all the data into a ballistics calculator to get a idea of what to expect velocity, trajectory, and energy wise. When doing so I changed the BC numbers to match the Hornady SST and re-calculated. I was surprised with the results. Are these figures correct? It's hard to believe that there is this much difference between the two in velocity and energy at 200 yds.According to these tables the SST at 200yds is doing the same as the XTP at around 100yds. If that is correct those are significant numbers.
