[QUOTE="Bart B, post: 656842, member: 5302"] I'd skip any moderate load testing unless you plan on shooting only moderate loads. Save some barrel life and use close to maximum loads. I'd also skip OCW and Ladder Tests. Unless you shoot at least 5 shots with each load, the data you get won't be very accurate. I think you would do better by trying 3 or 4 loads near max and shoot 10 to 15 with each. The results you get will have a higher probability of being the "best" in that load range. Or start out with the same load that hundreds (thousands?) used in competition when the .308 was "the" round for best accuracy through 600 yards with shoulder fired rifles. 168's, 175's, 180's and 190's shot the most accurate with 45, 44, 43 and 42 grains of IMR4064 in that order of bullet weights. This assumes your barrel's groove diameter is a few ten thousandths smaller than the bullet diameter you'll use. They typically shot sub 1/2 MOA through 600 yards and all but the 168 shot under 3/4 MOA through 1000 in good barrels properly fit to a decent built rifle. [/QUOTE]
