[QUOTE="Jon A, post: 217509, member: 319"] It’s a measure of the percent of powder/gases that go “down the bore with the bullet.” For example, a straight walled case has a relatively small case capacity and large bore capacity. By the time the bullet exits the muzzle there’s only a very small percentage of gas left in the case—most of it is in the bore. On the contrary, for an “overbore” case, with a relativley large case capacity/small bore capacity, when the bullet exits there’s still a large amount of gas left in the case itself, a much smaller percentage will be traveling down the bore with the bullet.
