Paintballs (Paint)

Paintballs are the consumable projectiles used in paintball, providing a visible marking medium that allows referees and participants to determine whether a hit has occurred. Each paintball is made from a gelatin based outer shell that encapsulates a water soluble dye fill designed to break on impact and wash out of clothing and equipment. Because they directly influence reliability and accuracy, paintballs represent an essential component of the sport’s equipment system.

Manufacturers produce paintballs in several grades tailored to different environments. Field or recreational grade paint is designed for general use and rental operations, where durability and cost control are priorities. Higher grade or tournament paint is typically formulated with a thinner, more uniform shell and a brighter fill to support consistent breaks and improved visual identification. Although all grades share similar basic materials, variations in shell thickness, dye opacity, and surface finish create observable differences in performance and handling.

Most modern paintballs are classified as .68 caliber, though actual diameters can vary slightly between batches and brands. Small variations in size and shape affect how well paintballs interact with barrels and bore inserts. Rounder paint with uniform shell thickness tends to produce more predictable flight patterns and improved grouping. Dimples, flat spots, or out of round shells may lead to inconsistent trajectories, reduced efficiency, or unexpected breaks inside the marker or loader.

Environmental conditions significantly influence paintball properties. Heat can soften gelatin shells, promoting deformation and affecting feeding reliability. Cold temperatures can make shells brittle, increasing the likelihood of breaking before exiting the barrel. High humidity may cause swelling or changes in shell elasticity. For these reasons, paintballs are best maintained in a cool, dry storage area, away from long term pressure or direct sunlight. Rotating bags within a case helps distribute weight evenly and reduces the risk of developing flat spots during storage.

During use, players and field operators monitor paint quality for signs of degradation. Patterns such as repeated barrel breaks, inconsistent flight, or visible shell imperfections often indicate that paint has absorbed moisture, experienced temperature stress, or reached the end of its usable shelf life. While adjustments to velocity or barrel sizing may help stabilize performance, severely compromised paint generally requires replacement to restore reliability.
