Let’s stop the debate right here.
If you’re still trying to seat and crimp your 9mm rounds in a single stage, you’re doing it wrong—and you’re leaving performance, consistency, and accuracy on the table. At Bullet Corp, we’re not here to sugar-coat it. We’re here to get you loading smarter, so you get the full advantage of our high-performance polymer-coated bullets.
The Problem: You’re Closing the Flare While Seating
Here’s the truth: you can’t close a case mouth flare and seat a bullet at the same time and expect perfection.
When you flare a case mouth (as you should), you’re prepping it for smooth bullet seating—critical for coated bullets like ours to prevent shaving or coating damage. But if you try to seat the bullet while closing the flare at the same time, the bullet WILL shift, tilt, or scrape. The coating may get compromised. Your OAL might vary. And accuracy? Forget about it.
This is reloading, not gambling.
“But I Adjusted My Die to Do Both…”
Sure, you can adjust a die to seat and crimp in one motion. But here’s the kicker: not all 9mm cases are the same.
-
Case length varies
-
Wall thickness varies
-
Brass hardness varies
So even if you “dial it in,” the results will always fluctuate. Unless you’re willing to trim all your 9mm brass to a uniform length—and let's be real, who has time for that?—you’re setting yourself up for inconsistency.
The Bullet Corp Way: Two-Stage Perfection
-
Stage 1: Seat the Bullet – Get your depth perfect. No tilt. No coating damage.
-
Stage 2: Taper Crimp – Close the flare cleanly and uniformly. Lock that bullet in without deformation.
That’s how you protect the coating, maintain your OAL, and achieve dead-on accuracy—round after round.
Bottom Line
If you’re serious about your reloads, about reliability, about getting the most from your Bullet Corp projectiles—seat and crimp in two stages.
It’s not just advice. It’s the difference between good enough and precision.
