Going to the range in an hour with the 300 Ultra and the Oehler 43. Pressure equipment is in place and I will be testing loads of RL25 and 180gr Scirocco seated at 3.660" in a range of 85gr to 97gr in .5gr icrements. Two skyscreens will be used to check BC's with one at the muzzle and one at 300 yards. At what point have you found a maximum load to be with this powder in a 180? I will find out soon for sure, but was just curious as to your findings and will check back before I leave, thanks.
