If the cases are all sized the same way, either in the same full length die or fireformed in the same chamber, then trimmed to the same length, you will find a direct correlation between weight and capacity.

It is much faster to sort by weight than capacity.

Well actually not always. After trimming to same length LC, Nosler, Norma 223 and 556 there was as much as 5 grains weight difference but case capacity only varied by 1.5 grains between them.

Okaaaay....Let's do some math, using your results.

A typical .223 Rem case weighs about 95 +/- grains. So a variation of 5 grains with an average weight of 95 grains would get a weight variance of +/- 5.26% .

A typical .223 Rem case holds about 28.8 +/- grains of water. So a variation of 1.5 grains with an average capacity of 28.8 grains would get a capacity variance of +/- 5.21%.

Hmmm......
