How would you adjust for the downward angle?
Do you know that ballistic calculation?
I use a rangefinder that accounts for slope. The only barrier I have now is my old eyes. Beyond 300 I’d be better off saving the ammo since my accuracy goes downhill. As far as ballistics I load my own rounds and have tried many different powders and bullets. Lapua brass is my go to.
I’m no sniper but I can drop an animal with accuracy 99% of the time. I missed 2 deer my entire hunting life.
