You can push the limits of equipment no matter what it is but that doesn't make it an effective tool for the task at hand. in the same vein you can drive a nail with the end of a screwdriver. I routinely shoot 600yards with a red dot and no magnifier with my 5.56 Ar's on ISPSC steel, but I can do that same thing with a mk12 100x more consistently. Hell, I've even hit a bird with a dasiy bb gun and iron sights at 300 yards once it was pure luck and I doubt I could repeat it if I tried, but If I made a video of that and posted it I guarantee you someone on youtube would see it and post how a dasiy is just as good as anschutz. Moral of the story, yes you can use off the shelf hunting rifles these days to do impressive stuff but please don't fall in to the trap of just as good mentality.
Here's a video one a guy doing ELR stuff with a 22.
