Bullets in flight have a few dynamical modes where they have a sort of wobble around the direction of travel. They all, when given enough distance, end up tumbling end over end which absolutely ruins accuracy though getting hit with a tumbling bullet is quite destructive for soft targets.
I can totally see trying for a record being helped with a low aspect ratio bullet (er, short and stubby) though this is probably not what you’d actually do if you were doing anything but trying for records.
Fun fact: if you don’t correct for the fact that the earth is spinning which requires knowing your latitude and compass direction, your targeting will be off by an amount measured in feet at this range.
I spent a while developing external ballistics models for a similar use case years ago.
