You didn't mention the weight of the bullet but if 158 grains 3.5 grains of Bullseye should be considered maximum. For 125 grain you can go to 3.7 -3.9 but stick with 3.5 with the 158 grain. I am currently loading 4.0 gr of 700X with some 124 gr LRN bullets and this is a nice load. Mostly I am trying to get rid of the last of a can of 700X as it meters terribly and has to be short weighed and topped off with a trickler.
