Welcome to the forum...a great place by far.
Nice paint scheme.
I use a Nikon Prostaff 3-9x40 and it works great at 100 yds...ammo can be iffy regarding great accuracy at 100 yds...My wife has a CenterPoint 3-9x40 on her 10-22 and it too is great at 100 yds and cost me $50 at a local gun show.
Most decent quality scopes are going to be just fine at 100 yards.
