While I do admit today's equipment is more available and well known, I still have a 1970's model 3x9x40 that has the BDC dial with plex wires on the crosshair. I used it to shoot fairly long distances on game. Also, there were several turret target scopes back in the day many of us used for LR shooting, comp, varmints, etc. My old 1,000yd turret BR scopes saw much usage on MR and LR P-dog towns, so even decades ago, there were many options for the dedicated LR shooter.
There just wasn't as many of us.
If we really take a trip down LR memory lane for the really old timers, I'm not there yet but getting close:
