[QUOTE="kiwi3006, post: 414384, member: 8927"] I would get a chrono. I have never chronoed a norma round so can't help there. But you should validate your drop chart as of course. ie shoot at 300 yds (see comment below). Compare where it is hitting compared with the drop chart. do the same for 600 yds and further is possible. Then tweak the velocity or BC until the drop chart agrees with your actual results. This assumes you know the barometric pressure and temp and humdity when you were shooting. Re 300 yds. I zero at 100 yds. Then I dial in my 300 yd comeup and shoot at 300 yds and adjust turrets so that I am zeroed at 300 yds. I then "zero" my turret so that it reads what the 300 yd comeup states. ie for my load my 300 yd come up is 2.9 MOA. I zero at 300 yds then zero the turret to read 2.9 (well actually 3 as it is a 1/4 MOA turret. Stu. [/QUOTE]
