[QUOTE="Shane Lindsey, post: 2330100, member: 25831"] I would not try and use less than what Hammer recommends. If anything overspin. I tried a 10.25 and a 181gr and no bueno. Those models are made more for the cup and core. These monos need the twist rate they recommend from Hammer for sure. As far as load data. With that bullet, take the Nosler manual for the 140s. I would start at 42gr and work up in one grain increments until you find pressure. Then back off a grain. Start with seating at .050" off lands. You could potentially be done with load dev in ten rounds. Five to find pressure and five more to check velocity. Then shoot for drops. Really with a couple of rifles it has been that easy. Some others, not so much. If you do not have the twist, I wouldn't waste the components trying to make it work. [/QUOTE]
