Even if you want to make ammo out of plastic, casting them is a lot less expensive. But as you basically need a hollow tube, you can just drill a hole in some plastic and even use woodturning techniques on a piece of plastic to give the shell the desired shape.
What is a polymer bullet?
Polymer-tipped bullets are a type of hollow-point bullet tipped with a synthetic polymer nose cone to give it a pointed spitzer-like shape. Most tips are made of polyoxymethylene, although some manufacturers have used polyester urethane-methylenebis(phenylisocyanate) copolymer.
Are polymer rounds good?
The polymer-tipped bullets worked really well in rifles intended for practical velocities and distances out to about 400 yards. Most companies' polymer-tipped bullets designed for the much-faster magnum calibers also worked well out to 400 yards.Nov 28, 2016
What are polymer tip bullets for?
Many plastic-tip bullets are also created to give greater aerodynamic performance to hollowpoint rounds, as adding the polymer tip can improve this aspect, resulting in a flatter, faster trajectory. The plastic can also drive into the core of the hollow point, expanding the round in the target.Mar 29, 2017
Are polymer tip bullets more accurate?
Polymer tipped hollow point pistol ammunition feeds more reliably in most guns (especially those designed to feed FMJ or round nosed projectiles). The sharp edge of an unprotected hollow point can catch on the feed ramp causing malfunctions. The polymer tip also allows the bullet to expand in a more predictable way.
What is composite-cased ammo?
Polymer-cased ammunition (PCA) is firearm ammunition (cartridge) with casings made from synthetic polymer instead of the typical metallic casing. PCA is considered a new alternative that potentially reduces production cost and weight for long guns and handguns.
Can composite ammo be reloaded?
Is your composite ammunition reloadable? No. True Velocity ammunition is not designed to be reloaded using commercially available reloading equipment. We do not recommend attempting to reload our cartridge cases.
What is a composite cartridge?
Composite refers to an all in one cartridge, toner dispenser and photo drum inside a case or "cartridge". Some models have a fixed toner dispenser and the photo drum is a separate assembly.Nov 26, 2017
Does steel cased ammo hurt your gun?
While I don't generally recommend steel cased ammo, it's not going to hurt your rifle in limited amounts. If used exclusively however it will reduce the barrel life by about 4,000-5,000 rounds. Most if not all of this ammo uses a copper coated steel jacketed “bi-metal” bullet which increases wear on the barrel.Jan 14, 2017
