Can anyone please help me with a couple load calculations? I am trying to prepare a sticker to put on my scope for hunting season to estimate yardage at each of the hash marks. I don't have a chronograph. I have the Viper HD 5-25 x 50 SFP scope VMR3-MOA reticle. My sight height is about 42mm (1.65in). I have a Seekins PH3 in 7PRC. I plan to hunt in Idaho around 3000-4500 ft. Zero at 100 yds. I am between two loads, so if you could send for each, that would be great. I did a ballistics calculator, but I don't know how to take that info and translate that over to my specific reticle.

1. Barnes 160gr LRX BT = 3050 fps
2. Federal Premium ELD-X 175gr = 3000 fps

Here's what I got from the Hornady site:
Bullet:HORNADY 7 MM 175 GR ELD-X
Muzzle Velocity (ft/s)3000
Wind Angle (°)90
Barrel Twist (in/rev)8

Do you need any other info from me? Thanks so much!
 
You need to know your velocity and confirm with practice at the distance you want to hunt. At this point youd be better off with a 200yd zero and keep your shots under 300yds max and youd be fine.
