[QUOTE="RockyMtnMT, post: 1964968, member: 7999"] I think this is the thread that I had mentioned that we are working on a new bullet. Well we tested today. We have a winner!!! We shot at 1008y today. What we saw from todays data is that the Absolute Hammer is running the same form factor as the Hammer Hunter. We were hoping that we were seeing a bit of an increase in bc, but I don't think so. I am fine with that since we are seeing huge increases in vel. We have yet to see how hard we can push these. We have not loaded to max pressure yet. Our 27" barrel 280ai is running this 148g Absolute Hammer at 3370 fps with no signs of pressure. As we develop the line we will start playing with how hard we can push them. The highest vel that Hodgdon shows for a 150g bullet is 2950 fps. We are running Peterson brass, so there could be some vel gain there. We did see about 300 fps increase in vel with the 22 cal that we tested too. So the bc that I come up with for todays data is .228 g7 at 1008y. We should have shot it at 700y. I am thinking the bc is probably a bit better with more vel. Impact vel at 1008y is 1730 fps. BC will drop as vel drops. The ogive on this bullet is a standard secant. None of our weird ideas out ran it. The 1st version multi radius ogive ran very close but not quite. We will move forward with the Absolute Hammer line with the standard secant and tangent ovives. We will continue to play with diff designs as we dream them up. Eventually we will find one that is working better. [/QUOTE]
