Out of the box or custom?

[Bill Allen]

What would be the difference in accuracy between say, two new Remington 700s (or whatever) : One used as the factory ships it and the other highly customized with a new stock, bedding and a barrel?

Since I am a hunter only, would all of the extra expense pay off for me? What would be the difference in groups at 100 yards or 200 yards? I need a new hunting rifle but I don't want to waste money nor short myself.

What guns shoot the most accurate out of the box?

Thanks.
