Had my sons 20ga out today starting the sight in process. 1st I bore sight, then I get it tweaked in at 25yds with foster slugs. after that I clean it really well. This was a scope change so I already know that it likes the hornady sst. with a new to you gun buy a bunch of different sabots and find out what it likes to shoot. I then go to 50 yds and tweak it in then to 75 yds. In my part of central N.Y. I like to sight in for 1 1/2-2 inch high at 75yds. I have only ever taken 2 deer at over 100yds and they were both in open fields, one was 115yds the other was 135 and I held dead on, both of them DRT. Hope this helps you!
