Lyman H & I improved sizing dies now have 90 degree hole spacing. It's now easy to lubricate bullets even with today's hard lubricants. Lyman sizing dies also feature a tapered mouth and hardened interior insuring alignment for perfect cylindrical shape. Interior dimensions correspond to suggested diameters for all popular rifle and pistol calibers.
This .457" die is ideal for .45-70 and .45-120 bullets to be used in Davide Pedersoli 1874 Sharps, Rolling Block rifles, and other rifles with very tight bore and groove dimensions. Most other Sharps rifles require a .458" or .459" bullet. Antique trapdoor Springfield rifles vary widely, and must be individually measured. Size your bullets .001" or .002" larger than your rifle's largest groove diameter, for best accuracy and minimum leading.
Use this die set in your Lyman or RCBS Luber-Sizer press.
