I recently started using Varget in my .308 with 168 grain sierra match kings. According to the Sierra manual, the max load for varget is 43.5 grains with a 168 grain SMK. I noticed that 43.5 grains is very conservitive compared to some of the other 168 grainers I’ve loaded. According to the chronograph, I’m getting an extreme spread of 70 fps with this load which leads me to believe that the load might be too light. By going up to 44 grains, the extreme spread goes down to 50 fps, but I’m hesitant to load it any hotter. I’m curious as to why nearly all other bullet manufactures publish heavier loads for the 168 grainers. I’m wondering if there is something special about the smk’s (more bearing surface?) that require a lower powder charge or if they put out overly conservative numbers.
