An open single-cavity bullet mold and a closed two-cavity mold. A cast bullet is made by allowing molten metal to solidify in a mold.Most cast bullets are made of lead alloyed with tin and antimony; but zinc alloys have been used when lead is scarce, and may be used again in response to concerns about lead toxicity.
Reloading the 8×56mmR Mannlicher can be problematic, due to the .329" groove diameter of the barrel. Commonly available .323" 8mm "S"-bullets will produce very poor accuracy. Open-base jacketed bullets, such as the .323" 244 grain round-nose FMJ bullets used in the 8×50mmR Mannlicher, will often produce better results but are difficult to obtain.
Standard .323" 8mm S-bullets are correct for this caliber though best results are obtained from open-base bullets that can expand to fit the .329" bore. [7] RCBS offers both reforming and reloading dies. When reloading for "wedge-lock" Mannlicher rifles such as the M.88, M.86/88, M.86/90 or M.88/90 chamber pressures should be kept low for safety.

The long-range ballistic performance of the 8mm Lebel bullet itself was exceptional for its time. For use in the magazine tube-fed early Lebel rifle , the 8 mm case was designed to protect against accidental percussion inside the tube magazine by a circular groove around the primer cup which caught the tip of the following pointed bullet.
