My 2 Cents
The 168 Serria Matchking has been around for many years and it has a proven track record. It is definitely a good bullet.
However a few years ago I switched to a 168gr Hornady A-Max. Sweeeeeet !!!
I have several .308's one with a three groove 1-12 Lilja Barrel and it prints a hair over 1/4MOA, it is not a rifle, it is a long range high speed precision drill !!
My factory barreled m-700 easily hold 1/2MOA, I have loaded very little for it, as my Lilja Barreled gun has a tight neck chamber, and I can't swap ammo.
My next move is to go into some serious load development for the factory gun, as I just threw some rounds together for a quick trip to the range and still have a few, just lucked onto something that printed well.
FYI my powder of choice is Varget, the primers are WW lg rifle, the brass Laupua.
Both Barrels are 1-12 twist.
Same bullet works pretty darn well in my Garands too
