A week or so back, I received 3 CDS elev dials from Leupold. Yesterday I was able to test the 5500' ele dial.

Purpose built Alaska Pre 64 M70, Custom by Lee Christianson (Redneck) and Charley Santoni
D'Arcy Echols Legend stock by McMillian
9.3x62
250 Accubond running 2606 fps, .8 MOA, 5 SD (60 gr Varget)
VX3 1.75-6x32mm with standard duplex reticle
CDS dial was marked for 2606 fps, 50 deg F, 5500' elev

Sighted @ 200 yds, 5144' elev, 50 deg, 24.38 baro

Shooting condition:
34 deg F
6565' elev
22.9 baro
6-13 mph winds switching from 9 to 4 from mostly from 7 to 5.
Fired from prone off 6-9" Harris bipod and rear sand bag.


Out to 350 yds, I had zero problems hitting any of the plates.

The turkeys, @ 385 yds needed the dial turned to 400 yds

The 400 yd plate needed the dial turned to 420 yds to get hits.

I got numerous hits on the 8" plate on the left @ 400 yds. We call this set up "Know Your Limits".

The 500 yd plates/Rams were a bit more of a challenge. Even with a spotter directly behind me, he had to walk me in to get hits.

Had to dial up 550 to get hits @ the 500 yd ram.

Even though the dial had a number 6 on it, the dial would not turn past 550.

What confused me was that I was shooting @ 6565' and the sight in elev is 5144'. I should have been hitting high as the air is thinner.

I ran my Droid Shooter ballistic program

Sight-in day

Baro 24.38
temp 50 deg F
500 yd drop = 48.7"

Shooting day

Baro 22.9
temp 34 deg F
500 yd drop = 48.1"

I should not have been missing either the 400 yd plates nor the 500 yd rams, low.

What do you think is the issue; parallax or the dial? Possibly a bad 200 yd zero. I'll check it next week!
