Default RE: SIGHTING IN

This will get you in the ball game. Got 2950 fps (just under max Hornady) using a 180 gr spire point.

max point blank range 319 yds
max point blank zero272 yds
offset @ 100 yds +3.3"

Bullet path:

125 yd +3.8" 2676 fps
150 yd +4"2623 fps
175 yd +3.8" 2571 fps
200 yd+3.4" 2519 fps
225 yd+2.6"2468 fps
250 yd +1.3" 2418 fps
275 yd -.2" 2368 fps
300 yd -2" 2319 fps

To figure energy: Vel x vel Divideby 7000 devide that by 64.32 multiply by the weight of the bullet.
ie: 2950 x 2950 = 8702500
devide by 7000 = 1243.2142
devide by 64.32 = 19.328578
multiply by 180 = 3479 ft lbs energy
