Warner Tool Company (WTC) has introduced a new series of “Flat Line” ultra-high-BC bullets. These sleek, lathe-turned solids are some of the most perfectly-streamlined projectiles ever sold. The Ballistic Coefficients (BCs) of Flat Line projectiles are as much as 20% higher than other match bullets of similar caliber and weight. For example, the .30-caliber 200gr Flat Line bullet has a claimed G1 BC of 0.780. Compare that to 0.555 for the Sierra 200gr MatchKing and 0.622 for the Berger 200gr Hybrid.
The new Flat Line bullets all show extremely high Ballistic Coefficients for their weights:

WTC also claims that Flat Line bullets can be launched at faster velocities than other bullets of similar caliber and weight. In its marketing materials, WTC says that Flat Line bullets deliver “Higher velocities when compared with projectiles in its weight class [and] much higher velocity when compared with projectiles of similar BC.” For example, WTC claims that “the 155.5gr .30-caliber bullet has the velocity of a 125-135gr bullet [with] the BC of a 185-200gr bullet.” It will be interesting to see if these claims can be verified in field tests.
Here are comparative G1 BCs for a variety of large .30-caliber bullets:
Cal Zant of the Precision Rifle Blog has obtained some early-production Flat Line bullets from their designer, Josh Kunz. Zant has written a lengthy article explaining the design and features of the new Flat Line bullets. If you are considering ordering some of these new lathe-turned solids, you should definitely read Zant’s report.

These bullets were designed by Aerospace engineer Josh Kunz using advanced computational fluid dynamics (CFD) to simulate supersonic air flow around the bullets. Through the use of advanced modeling and precision CNC machining, Kunz has developed extremely uniform, ballistically “slippery” bullets that fly faster and flatter than other projectiles of similar weight/caliber.
Premium Pricing: Flat Line Bullets Cost $125 to $165 per Hundred
These new Flat Line solid bullets are pricey. The 155s cost $1.25 per bullet and the price goes up from there. If you need large quantities of projectiles for a week-long match, the cost can be daunting. One hundred fifty of the 200-grainers will set you back $435.00! Here is a price list for the new Flat Line bullets. All quantities are in boxes of 50. Pricing is introductory and subject to change.
| .30 Cal 155 grain |
$62.50 per 50-ct box ($1.25 per bullet) |
| .30 Cal 180 grain |
$67.50 per 50-ct box ($1.35 per bullet) |
| .30 Cal 200 grain |
$72.50 per 50-ct box ($1.45 per bullet) |
| .338 Cal 255 grain |
$82.50 per 50-ct box ($1.65 per bullet) |
Is the cost worth it? When you look at the overall expense of attending a major match, and the fact that the top places in big matches are sometimes are decided by a single point (or X-Count), some competitors will spend the extra money for these ultra-high BC solids.
