Check out tnoutdoors9's xtp videos. He tests the 200 gr xtp and 230 gr xtp. Both are +p (which is every other manufacturer's standard pressure). Both expanded the same; 200 gr made 17.5 inches, and the 230 made 14.5 inches. If you compare the "wound tract" the 200 gr seems to have churned things up a bit more than the 230.
