Wondering about when testing reticle, with the T on the paper, Do you get the first shot in the middle by using the windage and elevation or are you boresighting , also if you are in the middle and you go up , and you are not on or close to the line are you moving the windage or elevation or the scope,to get centered again.... A little confusing, I shoot a 338 ultra mag and get consistent 5/8 to 3/4 " groups at 100yds, sometimes 300 is a little large like 4 inches..... never have tried this trick, just used the mirror thing and kinda eyeballed it. i can see having great groups at 100 and not at 3 4 and 500 yds.
also wondering what you do when putting a scope on getting everything straight and level
