I was doing a review on a Cooper Model 21 .223 single shot rifle about 30 odd years ago, and my handload using the then 53gn Barnes X bullet was sighted 3" high at 100 yards.
During a 'roo cull, I took out a 6 footer with a guessed 4 foot holdover. (2 over the head to allow for 2 more to drop into the chest) The upright stance was an asset during culling.
After a few more animals fell, it was a lesson in the value of a good bullet over the paper ballistics we all used to rely upon back then. Back then, the BC and SD would have been frowned upon for any long range work, especially for those that didn't do it.
Closest was a boar at around 80 yards also during a cull. He wasn't happy about it either, but once the first bullet connected he started clicking his tucks as they sometimes do until the second one hit home.
