Will going to the axis 400's drop my overall speed? Is this sufficent? Or should I goheavier? But since the season is right around the corner how well do you think the axis 500's that I an shooting will do ?How much does speed really account for? I do have a range finder just bought a leupold rx II camo. Pd 200 for it 100 bucks cheaper than cabelas and bass pro even with shipping added.
