Blazer ammunition, a line manufactured by CCI, often carries a warning against use in firearms equipped with ported compensators. Ported compensators redirect propellant gases upward or to the sides through openings in the barrel or slide, reducing muzzle climb and recoil. The caution stems from the specific propellant formulation and projectile construction employed in certain Blazer ammunition loads, particularly those with aluminum casings.
The primary concern is the potential for inconsistent performance and increased risk of malfunctions. The lower pressures generated by some Blazer loads, coupled with the gas dispersion caused by the compensator’s ports, can result in insufficient energy to reliably cycle the firearm’s action. This can lead to failure to eject, failure to feed, or squib loadswhere the bullet does not exit the barrel completely. Historically, aluminum-cased ammunition has demonstrated greater sensitivity to pressure variations than brass-cased alternatives, further exacerbating these risks in compensated firearms.
