Miller Short

"The .32 Miller Short resulted from many years of working with the longer cases — .32/40 and 8.15x46R.

"The first problem is keeping the powder in the cases. A high side-walled action, such as the DeHaas Miller action, though stronger and safer than the other type actions, is harder to load. Some shooters pick up the rifle from the rest as each round is loaded. This allows cases with open mouths to be loaded and does locate the powder; however, moving the rifle for each shot is not the best way to shoot good scores. The short case permits the use of a disk of brittle wad material that allows for normal loading and at the same time locates the powder. We find that the mean deviation from round to round with Accurate No. 9 and CCI primers, with the wad, will be down in the 2 to 5 FPS area. The case has the proper capacity for the bullet speed that we use in the Schuetzen game. Also, the long case tends to leak badly unless some provision is made to expand the necks for each shot. The .32 Miller Short is sized to fit and needs no further attention to seal. The .32 Miller was designed to use the 5.6x50R Mag case but also may be made from .357 Maximum case.

"The cases are selected from large lots and matched for weight before starting. The cases are placed upright in a flat-bottomed pan with water up to within 1/2" of mouth. With a torch heat each case until the mouth is red to the water and then tip it over to quench. Care must be taken to prevent melting the top edge of the mouth of the case. This is a very important step as the case will fold in the die and will not seal well in the chamber. The cases are formed in hardened press dies, using an arbor press, the excess length sawed off and filed flush. The base is filed flush and true, chamfered and pressed out. Primer pocket reaming and flash hole chamfering inside is done. This system results in Bench Rest quality ammunition. The accuracy of this system is well documented and is replacing the older cases that are hard to find and expensive."
