I'm thinking about investing in a chronograph. I've narrowed my choices down to the Pact Professional or the Oehler 35P. I typically like to test only a few (3 rnds) of each load when working up to max. When I think I'm there I'll do more extensive testing and accuracy evaluation. My main reason behind this is bullet cost. I have a expensive habit of trying the better bullets at $0.50-$1.00+ apiece. In past experience, with my buddy's Pact, I was sometimes left wondering if the posted velocities were always accurate due to lighting, battery cond., etc. In ten rounds I would always get an oddball. The ballistic tables that can be generated with the Pact are nice, but not absolutely necessary. I see the 35p's proof channel as a big plus. What are your thoughts?
