Forster dies are all that I buy any more.

I can tell the difference in .002/.008" runout in all my rifles. If you're talking about a 1.5 moa rifle then you probably couldn't tell the difference, but mine all shoot better than that with good ammo. In my experience going from .002 to .008" runout will at least double your group sizes.

If I'm seeing .008" runout then there's something wrong with my setup and I tweak it until it's fixed.
