Too late.......

Look, you got a new gun....you're Happy and excited as any kid would be, you go out and shoot it and it's probably the most accurate rifle you ever shot in your very young shooting life. I can understand that, but you got caught in a little fib that you have now turned into a big embarrassment for yourself. Just let it go and simply say "With all of the excitement of buying a new gun I might have exaggerated a little."

Or........you're one of the best shots I have ever heard of, shooting an old$130.00 rifle with a cheap scope and off the shelf ammo.[&:]
