46gr of Varget with either a 150 or 165 Nosler Ballistic Tip. Have not loaded anything else since I switched to these loads. I have used IMR4064 (46.3gr) and 2520 in the past but all my 308's shoot the Varget/Ballistic Tip loads so well I now use it as my standard load.
Here are some loads you can check out. If you tell me what bullet weights you have I'll see if I have any loads using those components. BTW the two best powders I've found for the .308 is 4895 and 4064. Varget and AA2460 also perform well. The burn rates for the 4 powders are all very close.
The standard load to duplicate the Military M-118 Match round is 42.5 grains of 4895. This load uses a 168 grain BTHP. It consistently shoots into about 1" in my HB .308.
I recently purchased some Nosler 140 BTHP rounds. Using 44.5 grains of 4895 and a CCI 200 primer I shot 2 five shot groups that grouped into .4 and .5".
I have been using 47.5 grains of Varget for the Speer 125 TNT. My 5 shot groups have been averaging .6".
I have used 45 grains of 4895 behind 150 Nosler BT. Most groups are less than 1". I have some into .5".
For deer and general big game hunting, I use a 168 gr ballistic tip loaded with Reloder 15. The 168 has a heavier jacket then the 165, but still expands well on deer. Years ago, I used 150 gr ballistic tips or 165 gr Hornady boat-tail spire points.
For bear or larger game, a 180 gr partition loaded with Alliant 2000MR gets over 2600 fps, which is about what many 180 gr factory .30-06 loads do.
