Lee 90087 Factory Short Bottle Neck Factory Crimp Pistol Die 22 Tuason-Craig-MicroMagnum (TCM)

The Lee 90087 Factory Crimp Die for 22 TCM pistol reloading brings match-grade ammunition consistency to your handloading bench. Unlike standard roll crimp dies, this specialized tool uses a collet mechanism to apply a straight crimp that seats bullets the same way factory ammunition does—firmly, reliably, and without risk of case buckling. If you're loading 22 TCM for hunting, competition, or serious practice, a proper crimp is one of the easiest ways to improve accuracy and ammunition reliability without guesswork.

The collet-based crimping action grips the case mouth and applies even, controlled pressure to the cannelure (or seating groove area), creating a uniform crimp that holds the bullet in place during feeding, firing, and handling. This matters more than it sounds: a firm crimp raises the pressure floor before the bullet begins to move inside the case, which flattens your pressure curve and reduces shot-to-shot velocity variation. The result is tighter groups and more predictable ballistics—benefits you'll see on paper and downrange.

One of the practical advantages of the factory crimp approach is that you don't have to seat bullets to touch the rifling to achieve consistent results. That freedom makes your handloading process faster and safer, especially if your chamber or bullet seating dies vary slightly. You're also not limited to cannelured bullets; even plain-shanked projectiles benefit from the crimp's firmness and uniformity. Combined with careful powder selection and standard Lee reloading discipline, the 90087 is a straightforward path to ammunition that feeds reliably and shoots better.

Frequently Asked Questions

Does the Lee 90087 crimp die work with non-cannelured bullets?

Yes. The factory crimp die applies pressure to the case mouth itself, so it crimps bullets effectively whether or not they have a cannelure. You'll still see accuracy and velocity consistency improvements with plain-shanked projectiles.

Can this die buckle my cases the way a roll crimp die might?

No. The collet mechanism applies controlled, even pressure around the case mouth. It's designed to eliminate the case damage and buckling risk that can occur with traditional roll crimp dies.

Is the Lee 90087 compatible with standard reloading presses?

The die is designed for use in standard single-stage and progressive reloading presses. Follow Lee's setup instructions for your specific press and reloading sequence to ensure proper operation.

What's the main benefit of using a factory crimp die over standard reloading methods?

A factory crimp improves accuracy and velocity consistency by creating a firm, uniform grip that delays bullet movement until pressure builds to a higher level. This creates a more stable pressure curve and reduces shot-to-shot velocity variation—benefits you don't have to achieve through trial and error or unconventional seating practices.
