The TDS reticle, an effect tool.

A couple of years ago I started researching scopes for long distance shooting. I wanted something that did not require adjustments and most importantly, it had to be effective. I found this in the Swarovski AV 4x12 with the TDS Reticle. (The only short fall I seen in this optic is the lack of a parallex adjustment.) Our friends at Swarovski have further complemented the reticle by providing customers access to an online ballistics program. The software allows the user to enter data about the load along with a host of conditions and finishes with a reticle analysis. I found this to be most helpful in understanding the bullet path with respect to reticle design, distance, and target size. The example is based on a load I shoot in my 7mm WSM. The target size is 3-inchs.
