I agree that the rejection conversations generally need to be face to face. On the other hand, I don't see putting someone to a great deal of trouble to meet just so I can say that we won't make it. I'm just as happy with someone rejecting me from a distance. I may have questions, but having them answered through e-mail is fine.
I've never fired a real rifle like you describe. I've fired a few .22 rifles, an SKS, and an old M1 carbine. Someday, maybe I'll get to shoot a high quality rifle.
