Maybe you need to step back and take the perspective of a new/novice shooter that can't afford new/better/custom equipment, and re-read the responses to equipment related questions in this forum. The impression given is that the sport is an elitist clique, where people with inexpensive equipment aren't welcome. The "welcome" is the equivalent of a golf clap; sure, come on on out, we'll make sure to humiliate you so that you don't come back. Not said directly, but the undertones strongly imply it. I can't count the number of times I've directed new shooters over to F-class and they've shied away because they were basically told/give the impression that their equipment wouldn't work at all at 1k. The message is rarely: "Come on out. Have fun, it doesn't matter how you do, you'll learn a lot". It's: "this is what is required to win, if you're shooting anything less, you're wasting your time and ours". Whether that is the intend or not is irrelevant, that is the message many are getting.
There is a difference between saying something won't be competitive and something outright won't work. Some of these people just want to go out and TRY shooting at 1000 yards. There is no intent to win. But, they aren't going to go out and try if they feel their going to be looked down on due to their equipment/performance, of if they're told their equipment won't get a bullet to 1000 yards.
