As a relatively new hunter. I did go out for both rifle and bow so far this season. From my perspective, I find it a bit hard to believe the explosion of crossbow hunters has had an impact on rifle season. From my own experience, you can own one of the most advance and expensive crossbows out there, but it doesn't mean you are going to get a deer. Sure, it is a lot easier, I wont pretend that it is not. But, even with a crossbow people still miss. There are other factors that an expensive toy cannot take away, when out in the field. I have been out over a dozen times this year deer hunting, had a good shot on one decent doe and missed. But, wind, scent, sound, pressure, and hunters hunting other game on public lands still makes this difficult. Some of this get's better with experience.
What I am saying, just cause anyone can go buy a crossbow, even a ridiculous one (trust me y'all gave me **** about it) getting a deer isn't guaranteed and doesn't seem any easier. Because it is only taking one thing out of your control, there are plenty of other things in your control you need to mitigate and then deal with what isn't in your control.
