[QUOTE="Monteria, post: 2780109, member: 115565"] Good points. GRT and QL default data both seem to be inaccurate for H1000. Both predict substantially higher loads to hit velocity and pressure and both over estimate case fill too. I even opened a brand new bottle of H1000 to confirm it wasn't just my "can in use". 77.5gr of H1000 gets me 2890 FPS from 225eldms at what I estimate to be 99.9% fill. Only because of Texas 80+° temp changes, I think I'm going to get mandrels and play with neck tension before giving my H1000 stash away. [/QUOTE]
