50 BMG Primers #35
The CCI Mil-Spec No. 35/50 Cal BMG primer provides the most reliable, consistent ignition. It’s built to military specifications and specifically designed for use in 50 BMG. CCI Primers are continuously tested and improved. As a result, today’s CCI 50 BMG primer is more sensitive, easier to seat, and more compatible with progressive and automated loading equipment than ever before. They utilize modern non-corrosive and non-mercuric initiator mixes for the cleanest burn possible.

Provides extremely reliable, consistent ignition



Fraser –
I use these exclusively for my semi-automatic .50 caliber rifle. Because they are manufactured to strict mil-spec hardness standards, they offer incredible peace of mind against accidental slam-fires when the heavy bolt slams forward.
Bowen –
When you’re trying to make repeatable hits at 2,000 yards and beyond, vertical dispersion is your biggest enemy. These primers give the most uniform ignition pulse available, which keeps my vertical spread incredibly tight. It’s the only primer I trust for ELR matches.

Bought a bulk sleeve of these years ago and kept them sealed in a climate-controlled locker. Cracked open a fresh tray last weekend and they performed identically to a batch bought last month. CCI’s manufacturing standards are unmatched.”
Hunter Hudson –
I was getting minor primer cratering with imported brands on hot summer days when working up maximum velocity loads. Switched over to the CCI #35, and the harder cup completely solved the issue. The primers look pristine even with heavy charges of US869.
Gavin Laurent –
I shoot a lot of bulk surplus WC860 powder, which can be notoriously hard to ignite cleanly because of its slow burn rate. The CCI #35 delivers an incredibly hot, robust flame that ensures complete powder combustion and leaves less unburnt residue in my barrel.
Cypress –
I use a heavy-duty press to feed my fifty, and dimensional variance in components can easily jam up the system. These CCI primers are incredibly uniform from lot to lot. They slide into the primer pockets with the exact same seating resistance every single time.
Rowan Jasper –
If you are reloading for a Fifty, do not compromise on primers. The CCI #35 is the absolute benchmark. I have loaded thousands of rounds for my bolt-action rifle, and the ignition is instant and 100% reliable every time.
Banff –
I load match-grade ammo for extreme long-range competitions. Pairing these primers with turned-neck brass and solid lathe-turned projectiles yields sub-half-MOA performance out past a mile. I won’t use anything else.
Forest Keith –
The quality control from CCI is top-tier. The priming compound is perfectly metered, and there is no sloppy, excessive sealant overflowing on the edges. They clean up easily and leave no aggressive, corrosive residue in the pocket.
Sawyer –
These primers feature a much tougher cup compared to standard commercial variants. They handle the incredibly aggressive strike of military-grade firing pins easily, completely eliminating any risk of pierced cups or gas leakage.
Finn Douglas –
Unlike some imported brands that can run slightly oversized and cause a headache during assembly, CCI #35s are perfectly uniform. They seat smoothly and snugly into the primer pockets of my premium Lapua and Peterson brass.
Beau Colton –
The sheer weight and inertia of a .50 BMG firing pin can lead to terrifying slam-fires or pierced primers if you use weak commercial primers. These mil-spec #35s are intentionally built with a thicker wall to mitigate that exact risk. Safety alone makes them worth the price.
Lawrence –
Took my rifle out for a winter precision shoot in freezing, sub-zero conditions. Huge powder columns can be notoriously stubborn to ignite when frozen, but the hot spark from the CCI #35 gave me instant, crisp ignition on every shot.
