IMHO: Probably many {average} home reloader's have had a hard time justifying the spendy novelty tools purchasing. [chronograph.] I know I have.
Chronograph is not a novelty item. They are actually a money saver if you are making precision ammo. For starters, without a chronograph, you will have to dope your loads by shooting at least from 100-500 yards in 50 yard increments and then plot the path/drop on a spreadsheet. With my chronograph and a cell phone app I can get into the 8 ring at 1000 yards from a 100 yard zero.
Then there is new powder lots.. all your old info may be off significantly with a new lot of powder. But with a chronograph you can work back up to exactly where you were before without burning up a bunch of ammo.
Also, a chronograph helps diagnose issues like erratic burns causing high extreme spreads. It helps indicate if you are getting close to maximum pressure.
The manual published velocities are often off by 150 fps or more in my rifles. Especially if you are seating close to the lands.
I would argue you are much better off owning a chronograph than upgrading equipment or buying components. They aren't much more expensive than a good set of dies...Heck one of my Forster micrometer seating dies cost almost as much as my gamma chronograph I got on sale ($115).If you are a serious reloader, or even just a hunting plinking reloader, you have to have one. It will pay for itself quickly.
Back before chronographs existed, they had to do what I said above, shoot at various distances and fit an arc to the discovered bullet drop. I doubt you want to do that or have the time and money to do that if you are on a budget.
I guess if you just want the gun to go bang and only shoot 200 yards or less you can get bye, but I would hate to have to start all over every single time I switched powder lots , shooting ladders again and re doping my loads.
There are a lot of tools I have that I would get rid of before I got rid of my chronograph.
