Bolt fitting question

[englishman_ca]

The OP asked if there were opinions on if having a tight bolt head would help with accuracy. Now that we have flogged him with a wet lettuce, I think that the answer might be ...no, no opinions. But a tight bolt head can cause other issues if out of spec.

My tuppence worth is that it probably doesn't have a measurable effect on shooting accuracy, but it certainly wont hurt it.
