Abstract
An improved cylinder and barrel configuration permits a reduction in the stress imposed on the throat of a revolver barrel thereby improving the strength and accuracy of the combination. The design employs some degree of sizing of the bullet directly in the cylinder thus permitting the barrel bore to be smaller and decreasing the jump distance from cylinder to barrel. The bullet sizing occurs at a lower velocity and over a greater distance thus providing better accuracy and permitting increased barrel stength.
