Consistent accuracy starts before the bullet leaves the barrel—and that begins with clean, burr-free flash holes. The RCBS 88146 Flash Hole Deburring Tool for 6mm & .243 caliber cases removes the manufacturing burrs that lodge inside case flash holes, which can disrupt primer ignition and throw off your shot-to-shot consistency. If you're loading precision rifle rounds and want to eliminate one source of variation, this is the tool that does it without fuss or guesswork.
The design is straightforward and clever: a self-centering pilot collar automatically finds and aligns with each flash hole, so you don't have to hunt for it or risk off-center deburring. An adjustable stop lets you control how much brass you remove, preventing over-aggressive work that could damage the case. Once dialed in, the process becomes quick and repeatable—exactly what you need when you're prepping brass for a large reloading session.
Built for 6mm and .243 caliber cases, this is a purpose-built tool that takes the guesswork out of flash hole prep. Whether you're loading for a match rifle, a hunting gun, or a varmint setup, cleaning up your cases at the foundation level pays dividends downrange.

Frequently Asked Questions
What calibers does this deburring tool fit?
The RCBS 88146 is designed for 6mm and .243 caliber cases.
Why should I deburr flash holes in my reloaded ammo?
Manufacturing burrs left inside flash holes can cause erratic ignition, which disrupts consistency and accuracy. Removing them is a form of case prep that helps standardize your loads.
How does the self-centering pilot work?
The pilot collar automatically locates the flash hole and centers the deburring tip without requiring manual alignment, making the process faster and more consistent across large batches of cases.
Can I adjust how much brass is removed?
Yes. The tool features an adjustable stop that lets you control the deburring depth, so you can remove burrs without over-working the case.
