About the Cortina Precision Bullet Flow System

Competition shooters concerned with extreme precision may choose to use a bullet tipping die to uniform the bullet tip for a more consistent BC. Others may use a meplat trimmer. This process is extremely time consuming. The Cortina Precision Bullet Flow System is designed to expedite this process on a Dillon XL-650 or XL-750. Erik Cortina actually has an autodrive which basically allows you to sit back and let the bullets be pointed without touching anything.

About the Rifle

I’m currently partway through my 7 PRCW F-Class series, having built the rifle, added an EC Tuner V2, and completed bedding and break-in. This rifle is designed for competition with a WOOX Titano, BAT VR action, and Brux barrel. I chambered it in 7 PRCW at Erik’s recommendation, a 6.5 PRC necked up to a 7mm that is all the rage in the F-Class world.

Loading Set-Up

Kyle installed the Bullet Flow System on a spare XL-650, starting with taking apart most of the system.

This isn’t really necessary, all you need to do is block the priming system, but Kyle decided on the XL-650 it would be easier to strip everything down. He installed the bullet shellplate first, which holds the bullets after they are dropped in, added a bit of grease, and checked system functionality.

He then chose to install the bullet extractor, bullet feeding die and Mr. Bullet Feeder.

Installing the Bullet Feeding Die

He had to make the caliber conversion to .308/7.62 and install the bullet flipper plate included with the Bullet Flow System.

Last was installing the Hoover bullet tipping die.

We had to call Erik for some advice on this one. Erik suggested crushing the bullet 0.001” at the ogive. Start by having the die touch the shellholder so the internal spring consistently presses the plunger.

Measure the ogive of the bullet and get 0.001” crush using the die. Then back the die off five clicks (0.005” per click).

When you’re finished and start processing bullets, you will be able to tell that the opening on the original bullet is slightly larger than on the tipped bullets. It’s recommended to trim the meplats before tipping, but we didn’t do that.

Pulling the handle is incredibly easy with not nearly the force required for sizing brass. This system worked flawlessly and was incredibly efficient. 


I want to take every opportunity I can to learn and expand my horizons. With 1,000 180 grain Bergers to tip, the Bullet Flow System with the Dillon XL-650 exponentially speeds up the process.

I prefer the priming system on the XL-750, so the Bullet Flow was a perfect use of my spare XL-650.
