New to CDs....

[Shifty05]

Ive had a few cds scopes for a year or two now and I just ordered a dial for my 300 win mag Tikka T3 (factory 180 ttsx). I have the vx 3i 4.5-14x50 1in mounted on it. I got this dial to hunt CA lead free and am going to get a dial for 180 factory accubonds for everywhere else.
My question is elevation. I typically hunt at either 5000ft or at sea level. I sent in that the average is 2500 but is it a waste of time? Should I order 2 different dials?
I’ve been playing around with reloading, dials, ballistics, etc the last year but I can’t seem to find a formula or rule of thumb when it comes to say sighting in at sea level then trying to determine the poi at 10000ft.
Thanks in advance

Go on Berger’s website and play with their ballistics calculator

Strelok has a free version of their ballistic calculator also.
Huge listing on bullets (G1 &G7), and scope reticles.

I use too many different bullet weights & manufacturers for CDS to work with.
I stick with MOA reticles & turrets.

Strelok will also let you zero for one load, and allow you to store other loads in for elevation of different bullet weights.

Example, i can zero my 257 Roberts with 120gr Sierra HPBT GameKings.
Switch over to 100gr Ballistic Tips, shoot & record height difference to Strelok.
Then when in the field, can bring up difference to zero scope if i decide to switch back.
