I started a stealthy sniper character a while ago, and set Strength to 4 since I planned on carrying a light load and wearing light armor. I did not know that the Sniper Rifle would "require" a Strength of 6. I never even thought about it until the Weapon Handling perk was offered to me, and reading the text got me to investigate a little and realized that I was too weak to handle the Sniper Rifle.
But what does this really mean to my character? How much difference does it make when one is too weak for a weapon?
I have Guns up to 90 at this point, and I miss long-distance sniper shots quite a bit - maybe 50% of the one made at the most extreme distances. Would the Weapon Handling perk, or two more points in Strength, make that much of a difference?
