My first MZ gun was a CVA Blazer which was about as primitive as it gets...lol. I think I paid about 50-75 bucks for it , new out of the box. it had no adjustable sights...lol. I can not remember how many times it misfired....it was a crap shoot, no doubt.
I believe that far fewer hunters would venture out with a flintlock and that does nothing but hurt the sport and limit the participants, imo.
To be honest, until there is a way to check every deer for proof of what the deer was killed with, hunters will shoot deer with modern weapons and say that killed it with a primitive weapon....
For every ethical hunter, there are many more unethical, especially hunting private land and online checkin.
The thing is this...how primitve is a bow these days? many bows are capable of being deadly at distance out to 70 plus yards....personally, i have never attempted a bow shot past 20 yards and never will, but my bow is not as MODERN as many are.
Modern inline MZs can shoot 200 yards accurately....amazing that they are still called primitve...lol.
There are a lot of WHYS in modern hunting......not sure we have time to go in to them all...just enjoy what you choose to do and let the rest lay peacefully....enjoy.
