So, I tried the Strelock app today that enhtr told me about. For my Zeiss Conquest Rapid Z600 I played with the different magnifications and found that a zero of 200yrds and a magnification of x8 put me where I wanted to be.

300 = 300
350 = 362
400 = 400
450 = 450
500 = 500
550 = 537
600 = 593
650 = 650

The Zeiss program says x7.57 and the Strelock program says x8. This is where I want to be going out to the range. :)

Now that my 7mm08 is wearing a Burris Fullfield II with a Ballistic Plex, I checked that out as well. Although Burris says that the optimum magnification is x14 to use the recticle (with +/- inches involved), the optimum magnification for my ammo is x11 with a 100 yd zero.

200 = 200
300 = 318
400 = 406
500 = 493

I've decided that I don't have enough time to practice and confirm this info therefore I will not shoot past 300 yds this hunting year and confirming the above info will be a project for the range next year.

[QUOTE=chuck;1663177]We've made this is all far to complicated really. /QUOTE]

Yes and no.

The minimum we must do is take the time to understand the BDC reticles, confirm and validate the actual subtension and bullet drop (and confirm calcoolator input data) in the field, and shoot at the extended ranges to confirm our maximum effective range. For some that is a given, for others that is too complicated. All that work...

On the other side, I would wager the majority of consumers of the LR goodies want products that are advertised to make them LR super heroes by simply entering a bunch of numbers into a calcoolator, subtend the scope to a given number or dial a turret, and bang away at animals. Instant gratification, but its not that simple....

Then there is the wind, which can complicate things, I suppose...

What do you mean?? I can't purchase an expensive high tech "shooting system" and become a sniper of game out to 1000 yards after just a few minutes at the range, or after a few minutes of instruction from an expert on the topic?.....I want my money back :)

nightforce offers a BDC retial in there front focal 3.5-15x 50 with LV.5 1000
hashes will not change with magnification. but bullet impact will chang with enviromental changes.
