[QUOTE="65WSM, post: 843412, member: 9551"] I will bet that the Chronograph is not set up parallel to trajectory. I use a magnetic level on my PACT chronograph to true it to the ground. If the set up is anything but parallel, then the distance is less between sensors and the readings will be high. His bayonet style chronograph is even more critical because the distance between sensors is so small. I have sensors 24 inches apart with the PACT. The Ohler has sensors at 36 inches and then at another 36 inches. Another test would be to see what the software programs say. What does Quickload say? When H-1000 was introduced, I bought 8 pounds immediately for use in my two pre-64 Model 70s, one with the original 1958 Winchester 26 inch barrel and one with a Krieger 26 inch barrel. 3180 (still under 3200) was the maximum I could load and get the primer pockets (Norma 7mm Mag brass) hold for another firing. With 129 Hornadys it was hard to get to 3300 fps and reload the brass with H-1000. [/QUOTE]
