Just checking to see what you guys are getting for velocity in 158 XTP handloads since the Hornady book's velocities were done with an 8" barrel. It says 1200 FPS with and 8" barrel is max with 14.3 grains of 2400.
With 13.5 grains of 2400 my 4" S&W 686 averages1175 FPS. Some went over the 1200FPS mark. I figured Id better stop there if I was getting near max velocity for an 8" with a 4".
