CCI 50 BMG Primers #35 Box of 500 (5 Trays of 100)

Clear Product Overview

CCI 35 50 BMG Primers are military-grade primers specifically engineered to meet the extreme pressure, ignition, and safety requirements of the .50 BMG cartridge and its wildcat derivatives. Built to rigorous MIL-SPEC standards, these No. 35 non-corrosive, non-mercuric primers feature thick, heavy-duty metal cups formulated to prevent slam-fires in semi-automatic platforms (such as the Barrett M82A1/M107) while withstanding massive chamber pressures. Designed to deliver an exceptionally hot, sustained flame blast, CCI #35 primers ensure complete combustion of dense, slow-burning heavy rifle propellants in large-capacity cases.

Real-World Use Information

When assembling match-grade or tactical rounds for extreme long-range (ELR) shooting using massive powder charges (such as Hodgdon H50BMG, US869, or Vihtavuori 20N29), CCI 35 50 BMG Primers provide the flame power required for consistent ignition. Their specialized heavy cup construction prevents cup cratering or piercing under extreme pressure spikes while seating cleanly into large .50 BMG primer pockets using specialized heavy-duty press equipment. Furthermore, the clean-burning initiator compound reduces heavy carbon buildup in flash holes and muzzle brakes.

Compatibility & Requirements

• Cartridge Compatibility: Fits standard .50 BMG primer pocket cases (.50 BMG, .416 Barrett, .460 Steyr). Note: Does NOT fit standard Large Rifle or Large Rifle Magnum pockets.

• Equipment Compatibility: Requires 50 BMG-specific press setups and heavy-duty priming equipment (e.g., Lee Precision 50 BMG kit, RCBS AmmoMaster 50 BMG, Hornady 50 BMG press).

• Safety Requirement: Always wear protective eyewear, follow published .50 BMG load data strictly, and store primers in a cool, dry location away from heat sources.

Pros & Limitations

Pros:

• MIL-SPEC Cup Hardness: Hardened cup minimizes the risk of floating firing pin slam-fires in semi-automatic .50 BMG rifles.

• Massive Flame Output: Produces an exceptionally hot, long-duration ignition blast for heavy charges of slow-burning powder.

• Extreme Pressure Resistance: Built to safely contain high peak pressures without cup perforation or primer leakage.

• Non-Corrosive Compound: Protects costly heavy-rifle barrels and chamber walls from corrosive pitting.

Limitations:

• Specific Equipment Needed: Requires dedicated .50 BMG size reloading equipment; cannot be seated with standard pistol or rifle priming tools.

• NOT for Standard Rifle Cases: Dimensional diameter is significantly larger than standard Large Rifle primers.

Frequently Asked Questions (FAQs)

Q: Can CCI #35 primers be used in standard Large Rifle Magnum brass like .338 Lapua?

A: No. CCI #35 primers are physically much larger than Large Rifle Magnum primers and are made exclusively for .50 BMG primer pockets.

Q: Are CCI 35 primers safe for use in semi-automatic .50 BMG rifles like the Barrett M82A1?

A: Yes, CCI #35 primers feature MIL-SPEC cup hardness specifically designed to help prevent slam-fires in semi-automatic heavy rifle platforms.

Q: How many primers come in a full box of CCI #35?

A: Unlike standard pistol/rifle primers that come in 1,000-count boxes, CCI 50 BMG primers come packaged in a 500-count box consisting of 5 trays of 100 primers.
