Yeah, crossbows haven't hurt the Kentucky hunting either. I bought a crossbow for my kids that couldn't pull the poundage on a compound to use during archery season so it would give them a chance to hunt. We shot it, and honestly, it's a little aggravating compared to a vertical bow. It's heavier and the time between shots was slower. Also, I don't think the practice/shooting curve is any different. I had bought a compound for my son, and he was shooting accurately to 40 yards within a few hours. I do the same thing every year. I shoot my compound, and I can shoot accurately to 60 yards in just a few shots. Modern compounds don't take the practice and time they used to. We spent more time dialing in the crossbow than we did the compound. And, on stand, you can hold these high letoff compounds for a long time. The crossbow, you have to have it on a rest to hold it for the same length of time. The gap between the two is narrowing.
I bought my wife a compound bow for christmas one year when she was about 55 yrs old. She had never drawn a bow in her life. We sighted it in that afternoon and she killed a deer with it the next day.
My son bought a crossbow about ten years ago - mainly for the kids. I decided I would use it one day since I had never killed a deer with one. Had a decent ten pt with a little palmation coming to a food plot and a sure enough good deer for here - a straight up ten pt close to 150. The smaller deer with the palmation came running in chasing a doe. Shot him at about 15 yards and 10 seconds later that big deer ran in. We are a two buck state. That big deer stayed within 30 yards of me for ten minutes and no way I could reload that loud cranking crossbow. Could have easily reloaded my compound and shot that deer at 15 yards. I had my 12 yr old grand daughter with me in a two man stand on one hunt. Biggest buck she had ever seen came in - she sighted it up - and couldnt pull the trigger. I had failed to snap the bolt in properly. I reached over and snapped it in and deer was gone. Son killed that deer as a nine pt next year - 148 1/2. It was a ten pt the year before
This is what I see with a crossbow as far as effect on the deer herd in our state. Hunters in our state kill 200,000 deer per year - give or take. Crossbow hunters only kill about 6%. Vertical bow about 15%. This year, our g&f allowed straight wall cartridge during our ML season - which I was strongly opposed to. ML hunters used to kill about 15,000 deer. This year, ML hunters kill about 14,000 and the straight wall hunters maybe 16,000 or so - but MG hunters killed a few less - for an annual total of just under 200,000 - same amount as without the 15,000 from straight walled cartridge hunters. All the straight walled cartridge hunters did was rob from the gun hunters.
You look at a lot of those more northern and eastern states and they are killing more deer with archery/crossbow than firearm. We kill 75% with firearm. It is like no matter the weapon, hunters are going to get their deer - with whatever weapon. I have probably killed Well over 100 deer with a compound bow, 25 with a MG, 2 with a crossbow, and 1 with straight wall during the straight wall season. Before my shoulder went south - I would have probably killed three deer a year with a spear if that is all I had.
I bought my first compound bow in late 70’s. My dad called it a “cheater”. Georgia had not legalized them yet. They were the last state to legalize compounds. There is a huge difference in killing ability of a recurve or longbow compared to a compound. My realistic range was about 20 yards with a recurve. It is about 35 yards with a compound - although I have take a couple out to 40. My son and his buddy have both killed deer just over 50 yards with a compound. Not me, but one of my family killed a deer at 45 yards with a crossbow. I have seen a doe “jump” the string at 45 yards with one of our ravin crossbows. The sound of a crossbow is LOUD and sharp
All that said, a crossbow is easier to kill a deer with more because you dont have to draw the bow in the presence of the deer. Our grand daughters usually start hunting with a crossbow - not because it is the most effective weapon - but because it doesnt make a loud bang. The younger kids can be noise shy just as much as they are recoil shy. Of course, they could not draw a legal compound anyway. I now spend some time hunting some public that is mostly bow only - with a crossbow - besides not killing my shoulder, I can hunt from the ground without lugging a climber around. I havent killed one yet - but not because I couldnt - I just chose not to. I do that a lot nowadays.
