I sighted in my 280ai at 100yds with factory Nosler 140 ABs this morning then shot at 200 and 300. My drops were about 3.5" and 13".
My average velocities the last 2 times out were 3270 and 3262.
I am no where near what the ballistic charts show for drops at 200 (2.2") and 300 (8.4"). I have to put in a velocity of about 2825 to get the drops to match. I am using a G1 BC of .485.
Any ideas?
