Matt Emmons arrived at the Rio Games confident. He was feeling good, shooting well, in the right frame of mind, felt like he had a shot at another Olympic medal.

He fell short and isn't exactly sure why.

"I did exactly what I wanted to do, exactly what I planned to do," Emmons said. "I felt good, mentally I felt really strong. I wouldn't have changed a thing."

Emmons arrived in Rio as one of the favorites in 50-meter 3-position rifle.

Despite a couple of gaffes _ a wrong target and an early fire _ he's had a strong Olympic career, with a prone rifle gold in Athens, a silver in Beijing and bronze in 3-position in London four years ago.

During qualifying in Rio, Emmons had a solid start in the kneeling portion of 3-position and was perfect in all four rounds of prone. Once he got to the standing series, Emmons struggled, missing 22 targets in the four-round series to finish 19th.

"In standing, I just wasn't seeing the shots well," he said. "I would think, that's a perfect shot, that's exactly what I want to do and it's a 9.8 or 9.9, just out of the 10-ring, and they weren't making sense. I just couldn't get the shots to go where I thought they would."
