you are correct, your friends need to learn how to shoot their guns

It's the Indian, not the arrow.
Yeah, but I'm gonna have to say that shooting a bow with a wider brace height and a single cam is generally going to be easier to shoot accurately than the latest double cam firebreather which strips skin off your forearm as often as not...
Case in point, when I was shooting quals with a lightweight commander, it was far easier to shoot a possible than with the current M&P 45c. Both are certainly achievable, but one is a helluva lot easier for this Indian.
Pretending the arrow doesn't matter is just naive IMO.
