If you have both barrels. How much fps do you gain from the 700mm vs the 600mm, with same setting and ammo and only changing the barrel. I'm guessing 30-40 fps more? Do you notice better accuracy with longer barrel? I just want to know so I can consider is it worth it to upgrade to a longer barrel.
