Hornady New Dimension Series II Three Die Set for .38, .357, and .357 Max 546527 utilizes a bevy of unique features to create an effective and efficient reloading die. Create perfectly aligned ammunition every time with the sliding alignment sleeve, which aligns the case neck, bullet, and seating stem in place before the bullet enters the case neck. Fine-tuning is easier with the Hornady Zip Spindle, an integral part of all New Dimension dies, which threads the spindle and spindle collet to reduce slippage and make it easier to tighten the spindle lock, something also made easier by the Hornady New Dimension II .38 to .357 Three Die Reloading Set's wrench flats. The headed steel decap pin in this Hornady gunsmith and reloading kit will never bend, break, or crack, and the polished elliptical expander reduces neck stretching. When a bare bones gunsmith and reloading set won't do the trick for your .38, .357, or .357 Max ammunition, load the Hornady New Dimension II 3 Die Set for .38 to .357 Handguns into your press!
