I own and hunt with a flintlock, a percussion and an inline throughout the year. My favorite is a flintlock and if I have cheated iron sights, it is because I added a peep sight which greatly aids my aging eyes. My inline is a TC Encore and with a scope. That 'rifle' is easily a 250+ yard killer while I limit myself to 150. Take away that scope and I am hesitant to shoot over 100. Where I hunt in PA I can have shots out to 500 yards or 20. I carry my Encore more than my .308 during rifle season these days because it is more of a challenge and just more satisfying to take a deer with it. When I've got an archery buck, I hunt doe with the TC side locks through rifle season. That's my choice.
To me, a 'traditional' or 'primitive' season is all in the word used, not it's dictionary definition. Change the terms to 'loose black powder' only and it is an entirely new meaning. Further amend it to 'open sights' only and there is further narrowing. Go one more step to 'iron sights' only and you have removed optic tubes and peep sights etc. (which were illegal in PA for decades). Now you have punished hunters with failing eyesight. But, definition of and intent of the words used is critical.
Scope limitations? I'm good with that and could see limits such as 1x fixed being the only legal scope. It does not overly aid the hunter but it could be the difference in humane kills. Removing scopes does not take away any hunting days but modifies how and with what you hunt. Modern inline muzzle loaders are highly effective. You cannot argue that. It is, as some said earlier, an early single-shot rifle season.
I equate inline hunting with scopes vs traditional flint/cap muzzle loaders to a special week for crossbow only, with scopes, following 'traditional' archery season... what is the difference? Vertical compound bows are far more deadly than a 'primitive/traditional' recurve. Make a recurve only season out of the first half of the as-is archery season and watch the hunter numbers swell.
CorbLand makes great points. The advancement of everything from weapons, ammo, clothing, technical gear, GPS, hunting aps, weather monitoring, scents and lures...and on and on, give any hunter a massive advantage that did not exist 20 years ago, let a lone 50 or 100.
You cannot have your cake and eat it too, nor should you be eating someone else's cake while hording your own. Facts and math are real and cannot be argued. Objective and critical thinking needs to be the norm, not reactionary rhetoric, which is all too common these days.
Disclaimer: I archery hunt with a crossbow now because I cannot pull a compound due to physical injuries. I choose to use it because it is legal here and it gets me hundreds more of hours in the field. If I wanted to hunt another state that did not allow the crossbow, then I wouldn't hunt that state. Simple if even disappointing. I am pretty firmly on the side of using whatever weapons are legal in a state for a specific season. I do not believe in semi-auto rifles for big game. Personal opinion. I think muzzle loader seasons should be 'traditional' loose black powder, no inlines. I don't make the laws but I abide by them.
Money is the driver here. Once the firearm industry got the first inline rifles to market they were lobbying hard in all states to legalize them, for $$$. The firearm industry drives far too much political and hunting law across all elements of daily life.
