Seems daunting but can easily be boosted on custom games with bots. Just make sure you don’t activate the ‘advanced settings’ as this blocks achievements among other bits.

For longest distance kill, i advise playing with a friend and boosting this on the map Dolomiti. Have them stand on the mountain, and you shoot them from the Defender spawn. Think it’s about 350-400meters. Don’t think any bot will top that.
