On the whole, I'd say that Remington makes some of the best "basic grade" ammo out there. I've seen their basic stuff make mediocre rifles do great things, and good rifles do better. (Strangely, the most impressive incidents of this I saw were with heavy roundnose loads: .303 in 180 RN and .257 in 120 RN. I would have thought that those would be lower accuracy, but they sang out of those two rifles.)
Sucks to lose a good one, especially if you hunted hard for him. I have to say, it's utterly worthwhile to check every round before going in the field. This means see that all chamber, stand on a table without rocking, and passing a visual inspection, front and back.
Now, please don't get defensive, but are you certain that your firing pin didn't come out short? Sometimes this can happen when crud builds up inside the bolt, and you'd never even notice it without disassembling and cleaning the bolt. I've had misfires from this before.
