Re: 308 W case capacity
55.7-55.8 for Lapua (in my guns), 57.1 for Winchester
That might be something worth putting together and pinning, or adding to the .308 load thread - a list of case capacities of all the commonly available brass - Remington, Federal, Norma, Black Hills, Nosler, etc. I realize some of these are duplicates (made by the same company), but the question seems to come up often enough...

Re: 308 W case capacity
Not wanting to make a mess with water I do it using fine powder. Results are very repeatable.
Capacity is determined by filling a sized, primed and trimmed cases with H335 as follows and weighing the charge:
1. Using a Lee dipper of the largest that will not overfill, pour powder slowly down the side of the funnel into the case.
2. Tap the case base lightly on the table three times to settle powder.
3. Fill the rest of the way and tap gently again three times.
4. Hold the case over the can, fill to overflowing, and wipe level with card.
5. Pour charge into pan to weigh averaging at least five cases.
Case Charge Percent
RP 59.1 1.00
WW 58.5 0.99
LC 57.5 0.97
Federal 57.3 0.97
LC Match 57.1 0.97
WRA Mil 57.1 0.97
Most of my military cases are quite old dated back to the early 70's.
