Speer Hot-Cor .358 180 Grain Spitzer Soft Point Rifle Bullet 100. The bullets are created using a "melt" process in which molten lead is poured into the copper jacket. Through the art of cold swaged forming the jacket is a much tougher material than the lead core material. Because of this the bullets expand more efficiently and thereby creating a larger wound channel. The firmer the lead core and softer the projectile the hotter the projectile and therefore the better the accuracy. All this makes Speer Hot Cor bullets preferred bullets for hunting big game but also for long range shooting for target or hunting depending on the distance and type of game. They are also one of the most popular bullets used for bench rest shooting as well as for target shooting but with the addition of a hollow point design and a full hollow point the Hot Cor leaves the barrel without any damage to the bore.
