You should either test you load at a range you will be shooting to learn the drop or use a ballistics app like JBM to work it out. Even then unless you have a chrono I would suggest field verifying the drop. This confidence and the correct setting on your scope or hold over will make shots on game seem like cheating.
The problem is that I've only got access to a 100m range. Ideally I would have found a flat spot out bush, and have targets set up at 100-500m at 100m intervals and shoot 5 shot groups and work out my dope that way. But I don't have a rangefinder nor is my range estimation skills any good. Another issue is that my barrel is a sporter and it heats up fast. 1 5 shot group is alright but another 1 straight after would be "praying and spraying".
You know you're alway welcome out our way if you can find the time to head out.
