Justin,
Thank you for a well written article. You pointed out some creative uses of elevation turret labels. There are applications to windage and side focus knobs as well. I think the applications are endless. I've done a little testing and agree with you that the CTS labels are quite durable.
CTS now has a ballistic calculator in the CTS label builder. The bullet drops matched my ballistic calculator (based on JBM) for the loads that I checked. That's convenient for people who don't regularly use a specific ballistic calculator.
What I like about CTS labels is that the label builder software is so easy to use. It takes about an hour to create a label from scratch. The end result is a great looking turret at a price that anyone can afford. Then if you move the scope to a different rifle, change loads, or go from 1,000 ft to 9,000 ft elevation, the cost of a new set of labels is only $25.
I've read several posts by people who have developed their own turret label making techniques. People have been using white label paper and a Sharpie for years. While it's certainly possible to design a label using general-purpose graphics software, that's a time-consuming process. Getting a label to wrap around the turret and be accurate from one end to the other would take a lot of trial end error. The CTS software does all of that for you.
