Heres my data:

6.5x284 140gr Berger VLD, 8 twist barrel

728 yards 200 yard zero, 14.6 moa up.

1010 feet elevation, 84 degrees, 56% humidity, scope height 1.75".

I think that's everything,

Thanks

Using the G7 Ballistics Calculator on this site, I get 2846 fps.

I use Ballistic FTE, G7 Br2 RF, and, BOTW, and NF. Get the similar data using all programs. I use G1. I also shoot and have field tested actual drops with my 6.5x284's. For your conditions., at 2832FPS I get a drop of 14.58. I am using around 53 gr. of H4831sc. I get 2941 FPS with this load in my Savage LRH.

I know this powder is not very temp sensative but how much velocity change can I expect going from say 105 degrees to 85 and all the way to 30 degrees Fahrenheit?

Thanks

I don't know what the velocity difference is but I have found that under 500 yards my impact for hunting is negligible. One click downward for each 25 degrees colder out to 700, 2 for each 25 between 700 and 1000. My clicks are .33moa. This works is for me with my turrets.
