Well here is my 2 cents on the subject...for what its worth
I used to shoot competitive archery with traditional equipment. Now you want to talk about a bunch of fellas proud of thier custom equipment
And you know what I learned its the wingnut behind the string that makes the diffrence!!!! All the money in the world doesn't matter if you can't shoot.
I agree that a off the shelf rifle probably won't in its orignal state shoot with a 10,000 custom rifle, but I have seen 1500 dollar guns blow the doors off full on customs in the right hands.
What I see with true custom rifles are the chance to own working art. You need to appreciate the work and dedication that went into the rifle and having the best components money can buy sure doesn't hurt, but I for one don't have deep enough pockets to own a 5000-10000 work of art, but dont tell that to my targets!
