I HAVE HAD MY 308 SURVIVOR FOR A YEAR NOW, AND I LOVE IT! AS FOR AMMO I HAVE TRIED OVER 10 LOADS, AND THE BEST I CAN FIND IS THE FEDERAL VITAL SHOCK NOSLER BALLISTIC TIP, BUT ITS ALSO PRETTY EXPENSIVE. AS A CHEAP AMMO THAT SHOOTS ACCURATLY I LIKE THE FEDERAL POWER SHOK, AND THE REMINGTON CORELOKT. THEY BOTH SEEM TO SHOOT PRETTY GOOD AT 100 YARDS. FOR MY GROUNDHOG, AND DEER HUNTING OUT PAST 200 YARDS I USE THE VITAL SHOKS. I CAN HIT GROUNDHOGS AT 400 WITH THEM. I DO NOTICE MY GUN DOES SHOOT A LITTLE BETTER WHEN THE BARREL IS A LITTLE DIRTY? CANT UNDERSTAND THAT BUT IT WORKS.
