I have shot the Hornady FPB the last 2 years from my TC Omega. Shooting 100 to 110 grains of triple 7, I killed 2 elk and a 5 x 5 mule deer in Colorado. I went from the power belts to the FPB as the power belts did not hold up on elk sized game. Since you can't legally shoot any type of sabot load in Colorado, over the years we migrated from conicals (Hornady Great Plains, Maxi-balls, Maxi Hunters) to power belts. The power belts group well, but fragment too much for elk. I'm sure they would be fine for whitetails, but I'm sticking with the FPB's for elk. Fantastic mushrooming, do not fragment on impact (like the power belts did).
