Is the Remington ammo a good quality ammo?
You're kidding, right? Seriously, I don't think this is even a legitimate question to ask about the major ammo manufacturers (Winchester/Remington/Federal/Hornaday). It's all "good quality" ammo, it's just a matter of your gun probably shooting one brand better than the other - my Remington rifle prefers Federal ammo over Remington in 150 gr ammo (the $15/box loads - not the higher dollar stuff).
