[QUOTE="Trnelson, post: 1224423, member: 42308"] I usually weight sort all of my brass for each rifle. In a magnum case like the 300 win mag you can probably get away with +/- 4g without seeing much on terms of velocity and accuracy. In .30/06 I've seen remington cases as light as 179g and military surplus brass as heavy as 208g. You can readily see that there's going to be an issue if one is attempting to treat them all alike. Pressure = force / area Less area and equal force will yield more pressure which directly correlates to an increase in velocity, provided it happens in the barrel. [/QUOTE]
