Leupold Var-XIII bites the dust.
I had heard crossbows were hard on rifle scopes. I had a Leupold Var-XIII 1.5x6x32 bite the dust. I had about 200 shot on the crossbow with this scope. My groups at 50 yards started opening up to 5-6 inches and going left. Groups keep growing and moving left. Checked mount and rings everything tight. Place the Tenpoint scope back on and went back to 1.5 inch groups at 50 yards. Crossbow is a TenPoint Elite about three years old. I wish someone made a good crossbow scope that would pickup light as good as a Leupold VXIII or Bushnell 4200. The TenPoint scope does great for ranges but sucks in low light.
