Re: Hunting
The various loads of powder charge and projectile were sufficient ( to use RR reply to horsepower) for the chosen game.
People also employed more hunting SKILLS IE stalking, waiting for a favorable shot and KNOWING
Their firearm.
A flintlock has a long ‘lock time’ between pulling the trigger and discharge. A lot can happen in even a few seconds; your heartbeat, muscle tension, a breeze down range.
This is still a factor, although improved. The classic Mauser 98
My favorite , has a massive firing pin
Noticeably slower than a contemporary bolt action. WW1 it was said Germany had the best hunting rifle -98 USA best long range target rifle- Springfield and Remington Enfield and UK best combat rifle -SMLE
All firearms were expensive and dear in price and availability. A famous mountain man waited two years for his Hawken.
The mujahadeen in Afghanistan were still using flintlocks vs The USSR. Those rifles OUTRANGED
The Kalashnikovs!
The extinction of many species certainly shows a firearm is deadly.
The introduction of single shot shotguns in South America vs blowguns led to several monkeys
Being wiped out.
