Is it just me, or is the published load data, way outside reality?
Been working on some 44 sp and 38 loads.. using mfr and other published data, I'm getting 25-30% lower velocities. 200 gr cast hp over 6.6 of universal is supposed to be up over 950. I'm barely getting 700 using a 190 cast hp. Same with unique and bullseye. As bad or worse in the 38 sp. even looking at barrel length. (4" in both) something doesn't seem right. Or are the lawyers pushing the caution buttons for people publishing reloading data..
Changed batteries in the chrono. Even shot some rifle and factory loads and it seems to be pretty accurate.
