Case Capacity Winchester vs Lake City in 308Win
I am changing from Winchester Commercial to Lake City Military brass in my target bolt gun 308Win loads. How much LESS capacity can I expect in the LC brass and how much LESS of 44grs/4064 should I expect to load??

I think what most do is fill a case's with water to compare volume. But I bet some one here already knows the answer.

Water weiging them is the way to go.

I'd start at 42gn and work back up to your load.Mil brass can come in at 2gn less a times.for this is what I have found when I tryed it in 223.I worked one load one time that took 2gn's less for the same POI for a Rem case.To add to this win brass holds the most from any other brass from what I undersatnd and have found myself.

Weighing water from a case won't be too accurate in determining how much capacity the case has. Depending on how much out of round the case is, it'll have different amounts of room inside for the water.
Just weigh cases. For every 10 grains difference in weight, adjust the powder charge 1 grain. Heavier cases need less powder, and so on...... So you'll probably use 43 grains of 4064 under 168's. I don't understand why one would not use commercial brass when military match brass isn't all that good. It was probably originally fired in service rifles and they all have out of square case heads. Military teams tried reloading that brass but gave up; it never shot as accurate as new, virgin brass. I've fired thousands of rounds of military match brass and never picked up one to reload. Match brass was not made for reloading; too hard and not all that great in dimensional quality. |
