Looking through Dixie's catalog I noticed the chamber diameter given in the revolver specs is often smaller than the groove diameter. Uberti's .44 Walker, for instance, shows .440 land, .466 groove and .449 chamber measurements. Pietta has an 1858 Remington replica which gives .440 land and .446 for both groove and chamber diameters. I would think a revolver which has a chamber smaller than the groove diameter would tend to be less accurate than one where the ball is groove size when it enters the barrel. I seek enlightenment.
