I chronographed the Remington factory 150 grain cor-lokt today in the 308. they clocked 2832. I went one more grain on the 150 grain Partition load and the average went from 2729 to 2793. I am still one half grain below Max and that extra i/2 grain would boost it up to 2825 or right in that area. I already have my load for this fall, the one at 2729 but next time I may load it to the new load from today. This lasest load shoots a hair smaller group. This current load is 48 grains of Varget. The max in my Nosler manual is 48.5.
