Ok my quickload v3.6 just arrived and I already played with it enough to make my brain hurt. Actually the program seems simple enough however one thing has me a little confused. I have always been under the impression that seating a bullet closer to the lands or increasing the cartridge length will increase preasure. So I start dropping in my load info to see what the program gives me. I already have some retumbo loaded up behind the 150 Bergers so I wanted to check what QL would give me for preasure and velocity. I know what the seating depth is and the OAL so I entered that info as well (2.895). After I got all the data I thought I would see what happens to the preasure by reducing the OAL, seating the bullets further into the case and creating a little more jump (2.695) To my surprise preasure increased and so did the velocity? HUH? The only thing I changed was to reduce the OAL from 2.895 to 2.695. Presure and velocity went from 56524psi 3079fps to 62591psi 3162fps. What am I missing here? I will post screen shots as soon as I figure out how.
