Winchester Unprimed .22-250 Rem Brass Cases 100-Pack

Winchester Unprimed Rifle Brass Cases

Winchester unprimed brass cases are engineered to exacting tolerances, ensuring smooth feeding and reliable chambering in your rifle. These .22-250 Remington cases are ideal for handloaders who demand consistency and quality.

Manufacturing Excellence

During production, each case undergoes annealing—a heat-treatment process that produces the correct hardness. This balance allows the brass to hold bullets securely while maintaining the flexibility necessary for reliable firing. You may notice a light stain near the neck; this is a natural result of the annealing process and does not affect performance.

What to Expect

Unprimed cases may occasionally arrive with imperfect mouths due to manufacturing or shipping. This is normal and easily corrected during your reloading process.

Preparation for Reloading

Before loading, prepare each case by:

• Resizing the mouth to proper dimensions
• Chamfering the case mouth to remove sharp edges
• Deburring any rough spots
• Expanding the neck (optional, using an expander ball in line with your sizing die)

With proper preparation, these cases will deliver the consistency and reliability serious reloaders expect from Winchester brass.
