A "Bolter" is a term used in various contexts, but it primarily refers to a type of firearm or a specific mechanism in certain machines. In firearms, a bolter typically describes a weapon that uses a bolt-action mechanism, where the shooter manually operates the bolt to load a cartridge into the chamber. This design is known for its reliability and accuracy, making it popular among hunters and sport shooters. In a different context, "Bolter" can also refer to a person or animal that suddenly runs away or escapes, often used in horse racing to describe a horse that breaks from the pack. This term highlights the unpredictability and speed of the subject, whether it be a horse or another entity.
