If you had a Garmin Xero, this may have been avoided.
“Seemed hotter” is not a standard unit of measure. A Garmin would have told you exactly what was going on.
If the previous bullet was lodged in the barrel, the Garmin would not have registered a shot, and maybe you would have stopped to investigate.
If the previous round was too hot, the Garmin would have told you and maybe you would have stopped. Maybe all the rounds were hot. No way of knowing.
If you don’t have a chronograph, you don’t have a clue what’s going on. I’ve seen reloading resources state velocities as much as 200 fps lower than what they chronoed.
Garmin are cheap. There’s no reason in the world for not everyone to have one.
