Warner Tool Company “Flat Line” Projectiles

Werner Tool Company - 660x300

Warner Tool Company (WTC) is specialized in manufacturing of precision long range shooting products. They produce precision rifle sights, complete rifles, reloading dies, shooting accessories and a line of bullets called Flat Line Projectiles.

Werner - bullet

Warner bullets are designed for needs of military special operation units and extreme long range shooters. They offer 7mm, .308, .338 and .375 caliber rifle bullets.

Here is a chart showing the weights, ballistic coefficients and minimum twist rates of all WTC bullets:

WTC claims that their projectiles’ performance exceeds that of competitors by about 20%. They also say that their bullets have higher BCs than others at any given bullet weight. According to WTC, each of their bullets shoots with as flat trajectory as would next lower weight bullet do, at the same time having a ballistic coefficient of the next higher weight bullets of competitors. In other words, Warner bullets have higher BCs and velocities as well as flatter trajectories than other bullets of the same weight. Of course, considering all other factors (barrel length, powder type and charge weight, twist rate etc.) to be the same.

Depending on the caliber and bullet weight, prices for Flat Line Projectiles vary from $65 to $85 per box of 50 bullets.

It would be interesting to see some technical explanation of how they manage to achieve such results, but there is no such information available yet.

I was born and currently live in Armenia, where I work in a family business of leather goods manufacturing. Being a retired sergeant of my country’s armed forces and a lifelong firearms enthusiast, I always enjoy studying firearms design, technology and history. Also my knowledge of Russian allows me to translate and make Russian/Soviet/Combloc small arms related information available for the English speaking audience.

    Those BCs are insane. Color me skeptical.

  • Vincent Mudde

    I’ve played around with Geoffery Kolbe’s bullet design form for a while, and i know it tends to overestimate high BCs, but I’ve not been able to replicate these BCs keeping with the given calibres, lengths, and masses. I’m inclined to call bullshit.

      I’ve played with the same program (that normally produces optimistic numbers), and I’m getting very close with the 198 gr 30 cal bullet, but only with very short bearing surface (this bullet is monolithic, surely with some kind of grooves) at high velocity, close to mach 3.0. I think over 1,000 yds or so the average BC should be lower.

      • Vincent

        I don’t know how much bearing surface is necessary, but surely you need more than one calibre’s worth. As far as I can see it’s usually closer to two.

        • Rnasser Rnasser

          Berger has about 1.3 calibers bearing surface in conventional lead core bullets, perhaps you can shave a bit more with front/rear grooves in monolithic bullets.

  • Walter E. Kurtz

    I know Alan Warner. He is a highly respected (and accomplished) long range competitive shooter and a master machinist. I don’t doubt the BC numbers. The man is a perfectionist and has probably forgotten more about long range accuracy than most of us will ever learn in a lifetime.

  • Bierstadt54

    Sounds good, but extraordinary claims call for extraordinary proof. Or any proof.

  • Michael

    If you’re claiming to know something about bullet design that a firm like Berger or Sierra doesn’t, you’d better have some good proof….

  • Christian Hedegaard-Schou

    “It would be interesting to see some technical explanation of how they manage to achieve such results”

    Using solid copper instead of lead, so you automatically get a longer bullet for the same weight as well as very long tapered boat tails and ogive profiles = much higher BC’s.

    That’s how they’re doing it.

      Yes, really no magic but pure logic, form factor for the win. I wonder that someone who writes a TFB article doesnt know what form factor means.

  • Adam Stevens

    The 180gr FlatLine has already been tested by Bryan Litz, his results were within like 10 points of advertised. .342 G7 if I remember correctly.

    • Rnasser Rnasser

      That number is veeery close to what the Kolbe program predicts, amazing for such a free program…

  • AD

    What’s with the weird blur on those photos?

    Know these since years. How does it come this post comes so late?
