For the most part the chrono could be dispensed with. Most of my shooting is under 200m. If I can print paper with a consistent group at 100m the rest is somewhat academic

However, I am also interested in being able to make an effective killing shot beyond 200m. If I can establish a reasonably approximate fps then of course I can get an idea of bullet drop and bullet energy at different distances.

But, its still not a huge deal to me. If I'm uncertain at 350m I'll get closer.

I have a place I can set gongs up out to 500m. With a large piece of cardboard behind. That exercise is arguably more important than accurate chronographing.

Nevertheless I thought it a useful question to explore.

Find a stable es charge and providing it shoots good groups varify velocity by shooting at longer ranges and calculate velocity by using the drop.
