easier holdover hiTs the ZeiSS ConqueSt 4.5-14x50mm mC riFLeSCope. eiss’ american Conquest riflescopes represent a good bargain for varminters, hunters, and competitors. almost half the price of their european models, but primarily produced with 1" instead of 30mm main tubes and 1/4" clicks, they retain most of the engineering found in the more expensive Victory series. While the glass produced for Zeiss’ Conquest and Victory optics are free of arsenic and lead, their proprietary advanced Optics system (aOs) allows them to cut the glass thinner, thereby reducing weight, and is so far used exclusively in their Victory series. the glass in the Victory series is also designed to slightly enhance color rendition and clarity over the Conquest. but the Victory costs considerably more as well. The move to holdover hash marks and ranging reticle designs has forced nearly every riflescope manufacturer to come up with innovative designs that lend a significant amount of flexibility to riflescopes. Not to be outdone, Zeiss enlisted the genius of two well-known American innovators, Mickey Fowler and Gerald Perry. Holdover systems are certainly not new, and creative ways to approach the opportunity surface every year. Simple is good. On the other hand, simple does not always solve all the opportunities you might like to take advantage of. The old Mil-Dot system, for example, is simple but sometimes a bit difficult to learn. Some reticles go to the other extreme, making the image look like a Venetian blind. Neither is bad, and some users who practice often accomplish phenomenal things with them. For the average shooter, a system that accomplishes his needs in a simple to understand and apply way, who has not the time to practice weekly or possibly even monthly, the reticle system must work the way he thinks. It has to be intuitive. As an engineer, I have seen the rise of sophisticated computer software replace the old “by hand” method to accomplish the mathematics required to solve Z JacoB Gottfredson Zeiss retains the european-style quick diopter focus (above). the turrets are designed like most target-style dials with 1/4" clicks and an even 10-mOa revolutions. a side parallax adjustment (below) is standard with this scope. the dials are reset to zero after sighting in by loosening the screw shown in the top of the elevation dial. Oddly, the dials turn opposite of most scopes. they are available in a hunting turret as well. the Conquest 4.5-14x50mm scope can be ordered in stainless finish (shown) or matte black. problems requiring billions of calculations. Some of them arrive at my office with manuals that would intimidate Einstein (Well… maybe not). But some are completely intuitive and use input data the way engineers were taught to think. The manual often sets on the shelf, gathering dust as the user completes design after design. In my humble opinion, the same should hold true for shooters. The progress taking us far beyond the old plex reticle is as much a boon for the shooter as computer software is for the engineer. Thirty years ago, the engineer had to make many conservative assumptions in two dimensions to complete a design. It would take him months of calculations. Once done there simply was not time to look at five or six alternatives or even one more, searching for the best and most economic solution. Today, the same problems are completed in three dimensions without conservative assumptions and done so in milliseconds. Alternatives can be explored and exhausted, looking for the best and least expensive design, all the while taking much less time than the old methods. This same technology is now available for designing optics and interior and exterior ballistics, making it fast and simple for the shooter to obtain data he can be use in the field. Now the 14 W W W.
