MOSSY OAK: I SHOOT A 50 CAL. WITH THE PERCISION SABOT THAT IS THERE QT'S 40 WHICH IS A 40 CAL. BULLET IN 235 GRAINS IN A BLUE SABOT THEY WON'T HURT THE GUN IN MY 54 CAL. I SHOOT THERE 45 POLY TIP 350 GRAIN IN A RED SABOT .PERCISION SABOT ARE GREAT BULLETS THAT IS A GOOD CHOICE FOR STOPPING GAME AND GETTING A LITLE MORE DISTANCE FOR THAT LONG SHOT.
