This may be a good exercise for folks that don’t know where their bullet is going to be.
If you can keep your bullets inside an 8” circle at 3 yards, you have the ability to not impact a chronograph. If you cannot, I question reasoning behind wanting velocity numbers.
I am not a Labradar hater, I like them. You need an extra trigger for things that don’t have enough blast. They take longer to setup than the chronographs I use most, they consume more power than most other chronographs (the one I use often, can run for years on a single battery) an extra power source should be purchased right from the start with the LR and the cost is often the largest hurdle for folks.
The good news is the cost is going to go down over time and they get better. The first TI Datamath calculator was $150, could display to 8 digits, ran off of 6 nicad batteries and could only add, subtract, multiply and divide. These days business give away calculators (free) that not only run off of ambient light but also have memory, square root functions, etc. It’s not instant though, requires a large enough target market and patents to expire.
