Plastic-tipped bullets are a type of bullet meant to confer the advantagof both spitzer and hollow-point bullets.
Description[]
They consist of a fairly normal hollow-point bullet with the frontal cavity filled in by hard plastic, which is molded into a streamlined shape mimicking the shape of a spitzer bullet. Upon impact, the plastic drives into the hollow point, or fragments into small pieces and the bullet performs like a regular hollow-point, expanding ("mushrooming") to a larger diameter or fragmenting. The end result is a bullet with the streamlined characteristics of spitzer bullet and the increased terminal mushrooming of JHPs[Clarification needed]. These bullets possess the aerodynamics for longer, more accurate flights, and the in-target performance to ensure high lethality.
Usage[]
Traditionally, these bullets are intended for use in rifles and single-shot handguns, as pistols are not normally used at the great distances where the streamlined ballistic tip is advantageous. However, a few companies produce pistol ammunition with plastic-tipped hollow points where the plastic is molded into a more rounded tip. These designs are not created to increase the streamlining of the bullet but rather to improve ammunition feeding in semi-automatic pistols that are prone to jams with regular hollow point ammunition. Examples of such pistol ammunition include COR®BON/Glaser's "Glaser Pow'RBall" line and Extreme Shock's "NyTrilium Air Freedom" ammunition (the "NyTrilium Air Freedom" cartridge also mimics the performance of Glaser Safety Slug cartridges, as it uses hollow bullets full of powdered metal designed to fragment rapidly on hitting a target).
Name[]
Ballistic Tips: Hornady 17 gr. V-Max 17HMR, .308 Winchester
"Ballistic Tip" is a registered trademark of Nosler, but numerous other companies produce similar projectiles, including Hornady[1] and Sierra. Nosler has always used a color code to indicate caliber on the polymer bullet tips, to make them easily distinguishable from each other: .25-blue, 6mm-purple, 6.5mm-orange, .270-yellow, 7mm-red, .30-green, 8mm-dark blue. Hornady almost universally uses red plastic tips (Hornady has produced .224" projectiles with blue plastic tips for use in civilian loads of FNH's proprietary 5.7x28mm cartridge). Sierra uses green and Swift uses black tips for their "Sirocco" plastic-tipped bullets.
