I know that some shooters can have bad experiances with any brand of bullet. It is more like one barrel particularly doesnt harmonicly like one type of bullet or another. That doesnt meen they suck. I for one have shot ALL of my personal best groups with hornady bullets. I have shot one .000" 3 shot group @ 100 yards with the 178 AMAX and more groups under .25" than I can count. My personal best group of 3.48" was also fired with hornaday bullets at 1000 yards. Trust me, these bullets will perform in most rifles.
If you are new to reloading, you may be getting alot of runout on your necks which can contribute to poor accuracy. Runout is when the necks become crooked due to full case sizing through an expander ball. You may need to get rid of the expander ball in the die and resort to another form of neck sizing. You may need to sort your cases by weight as well. Make sure you have a consistent powder scale. Also try the Federal Gold Medal Match 210 primers over the CCI.
BB said it best. Let the rifle tell you what it likes.
I will list some bullets you could try and I assure you one or more will make your rifle happy.
155 SMK, SCENAR, AMAX
168 SMK, AMAX
Also powders you should try are:
Varget is a great choice but I have owned 308s that didnt like VARGET either.
Long range shooting is a process that ends with a result. Once you start to focus on the result (how bad your last shot was, how big the group is going to be, what your buck will score, what your match score is, what place you are in...) then you loose the capacity to focus on the process.
