As you know, different types of ammunition have a corresponding special marking. First of all, it is needed so that the fighter equipping the weapons can choose the right ammunition, according to the requirements dictated by the tactical situation. Among other markings, bullets with a silver tip stand out. It's time to find out what they are and why they are needed. Obviously, they are not made for hunting vampires and werewolves.
You will have to enter from afar. In 1891, the Mosin magazine rifle, developed by the domestic designer Sergei Ivanovich Mosin, was adopted by the Russian Imperial Army. Together with her, the engineer created a new cartridge, well known to everyone who served in the military - 7.62 × 54R. This ammunition is one of the oldest among those used by the troops to this day. Like most other cartridges of the time, the 54th had a lead bullet. And that was his main problem.
The First World War showed what a shortage of ammunition is at the front, including ammunition for small arms. Among the would-be cartridges was 7.62 × 54R, since its production in large volumes turned out to be unexpectedly expensive. The situation needed to be changed. In 1917, a bourgeois and then a socialist revolution broke out. They were replaced by the Civil War. For a decade, the country had no time for rearmament.

The Soviet designers took up the 7.62 × 54R seriously in the mid-1930s, when it finally became clear that Europe was heading for a new large-scale war. The cartridge remained very expensive and difficult to manufacture, it was decided to make it cheaper. The solution turned out to be simple and ingenious. Engineers were able to replace the lead bullet core with a steel one. These 7.62x54Rs were significantly cheaper.

True, before the beginning of World War II, they did not have time to establish really mass production of the updated 7.62 × 54R. This happened only in 1953. The war was over, but the ammunition was still relevant. Since the warehouses had both lead-core cartridges and steel cartridges, it was decided to mark the bullets of the new sample with silver paint.
The updated 7.62 × 54R received the designation LSP (light bullet with a steel core). The cartridge is used to this day in such weapons as SVD, SVU, PKP "Pecheneg", SV-98 and others.
