Thread: Case capacity effects on velocity

I've been weighing my target cases.

The Lapua cases are noticeably lighter than the ADI and PSD cases I used before.

So this got me thinking, if you use the same amount of powder and the same weight projectile, what effect would a lighter case (assume it has more internal capacity ?) have on velocity ?

Asked another way, if you batch your cases and projectiles by weight, would you use the heavier projectiles with the lighter or heavier cases, and why ?
