I generally don't shoot over 40yds.When deer or elk hunting it's more uncommon than common to be on such a severe slope you have to use a pin other than the actual distance is. Shooting uphill for example, I've never come across a hill so steep that I had to use 40 yard pin for a 30-35 yard shot.

Now I have been on a hill where the animal was below me on a pretty steep angle and felt it was a little over 30 yards but used a 20yd pin. This was after I'd already missed one by going over its back the year before by shooting 35 yards for 35yards. All in all you'll know when it's so steep you feel like you're shooting out of a treestand! <grin> So I wouldn't be too concerned with worrying about making adjustments unless very, very steep!!-------------------ElkNut1
