My Savage 308 also likes 168gr AMAX on top of 44 gr of Varget. I've found that the 168 Matchkings shoot identical in the same load. I've always used Winchester brass and primers for no other reason than that they were cheapest and easiest to find.
Savage with a custom barrel for my "match" shooting.
Lapua Brass, Redding neck sizer (fire formed if new) to .307", 2.008" case length, weight selected cases when new
175gr Sierra HPBT, moly coated
2.211" length @ ogive for .017" jump
Federal 210M primer
Varget, for this time of year and this time of day, with 65° and 70ish% humidity it'll take somewhere around 43.2gr
Concencentricity must be 0.000" runout to be accepted and put into use, I have to use a custom seater die I made and an arbor press to achieve this.
On a sled, you will be hard pressed to note the holes at 100yd. At 1000yd, I can comfortably hit a 5" plate 95% of the time. At 1500yd, I'm on a 12" plate at least 80% but definetly out of glass at that point.
