I have bought every chronograph known to mankind, except the Oehlers(which I have used). I just don't want to mess with the cumbersome 3-screen setup.
I enjoy chronoing and handload for every caliber I shoot. I got tired of dealing with sun and wind problems. I solved the problem by buying a bullet trap and a PACT PC with infrared light source. It's set up in my shop so I get accurate results every time. You have to turn off all fluorescent lights and let fresh air in frequently. My nearest neighbors went to Florida so no one hears a thing.
Skip: I had a nice red Chrony that took a .223 hit from my scoped Mini-14. It moved downrange very smartly!
