Need trajectory / ballistic assistance
O.K., for any experts out there. Here is my situation. I've got a new Tikka T-3 laminated stainless rifle (in 270 WSM) to which I just mounted a Leupold VX III 3.5-10 X 40 gun metal grey scope. It has the B & C reticle. In the accompanying CD, Leupold recommends zeroing the scope at 300 yards for that caliber. Right now I'll be shooting Federal Vital-Shok 140 gr. Nosler Accubond ammo. I'd like to do some preliminary sighting in at my local rifle range, but they only have a 100 yard range. Until I can get somewhere with longer ranges, how high should I be at 100 yards to be close? My other thought was just to do the normal 2.5 inch high at 100 yards and then experiment later on. Any thoughts or suggestions? I have an friend with a somewhat similar set-up, but he zeroed at 100 and had holding points for approximately 200, 300, 350, and 400. I don't know if I like that or not. Any positive thoughts or ideas would be welcomed. Thanks.
