Can't speak for the sport, I got the V3 deluxe. I have used this chrony on rifle contours ranging from standard sporter up to 1" at the bore. The velocities have been spot on, and the drop estimate has been really close at 1000 yards. The estimate that the Vortex ballistic calculator has been around 1MOA off from the actual drop I've experienced. Granted the range I got the velocities from is around 80 miles away from the 1000 yard range, so the difference could be explained in the environmental factors. Overall this is an outstanding product. The only downside to this product is that it has a hard time attaining velocities on large caliber magnum handguns. My 5" 629 produced error.

There are other competitive options out there that might be considered as well.
You could invest in a lab radar ballistic chronograph. https://www.midwayusa.com/product/52...ar-chronograph
