Peterson Cartridge Introduces EZ-Seat™ Coating for More Consistent Neck Tension and Improved Loadability

 

Cranberry Township, PA (January 9, 2026) — Peterson Cartridge Co. today announced the introduction of its EZ-Seat™ Coating, a proprietary anti-tarnish and dry-lubricant treatment designed to deliver more consistent neck tension, reduced bullet seating force, and improved out-of-the-box loadability for precision rifle casings.

Developed through years of internal testing and data-driven analysis, EZ-Seat™ Coating addresses a long-standing and often misunderstood variable in cartridge performance: the surface condition inside the case neck after final annealing. During annealing, naturally occurring oxides form on the interior of the neck. These oxides can dramatically increase and destabilize bullet seating force, damage bullet jackets, and introduce neck tension variability.

“Neck tension is often discussed as a dimension or a press-fit,” said Derek Peterson, President of Peterson Cartridge. “What our testing showed is that surface condition inside the case neck plays an equally important — and often overlooked — role.”

Measured Results, Not Opinions

To convert customer feedback into quantifiable data, Peterson Cartridge invested in force-testing equipment to measure both bullet seating force and bullet pull force. Testing revealed that untreated annealed case necks exhibited high and inconsistent seating pressures due to oxide interaction with the bullet jacket.

With EZ-Seat™ Coating applied, results showed:
• Significantly reduced bullet seating force
• Substantially improved consistency (lower standard deviation)
• Reduced bullet jacket deformation
• Lower and more consistent bullet pull force

In controlled testing using 7 PRC casings from the same production lot, average bullet seating force dropped from approximately 272 lbs to 85 lbs, while bullet pull-force variation was reduced by nearly half.

Designed for Real-World Reloaders

EZ-Seat™ Coating encapsulates annealing oxides while providing corrosion protection and dry lubrication on both the interior and exterior of the casing. The result is brass that is ready to load straight out of the box, without requiring mandreling, tumbling, neck brushing, or lubricating prior to first firing.

The coating also reduces primer seating force during initial loading, further improving the overall loading experience.

“We know some reloaders will always run new brass through their own prep process,” Peterson added. “But with EZ-Seat™, they don’t have to.”

Proven Longevity

Before production release, EZ-Seat™ Coating underwent four extensive validation programs:

1. Coating compatibility
2. Coating concentration
3. Residue testing
4. Long-term aging

These multi-year evaluations confirmed the coating’s effectiveness both immediately and decades into the future.

Engineered for the First Firing — Where It Matters Most

EZ-Seat™ Coating is intended specifically for new, unfired brass. After the first firing, carbon fouling naturally lubricates the case neck interior, and neck tension becomes governed by brass hardness and dimensional press-fit rather than surface oxides.

Availability

Peterson concluded, “EZ-Seat™ Coating is now applied to all Peterson Cartridge rifle casings as part of standard production.”
