Do I have your attention yet ?

The more we explore the more we see how the little things can stack up. To many, the choice in the bullets they use can be a simple one. Cheapest, a specific weight, manufacturer, these short answers tell the story. As I noted, 2017 is truly the year of the bullet. As technology trickles down, the bullet is becoming a tipping point. Not just in the solid projectile market, better jacketed bullets are being released each month. Although Warner Tool has made 2017 the year of the Flat Line Projectile.

See if this sounds familiar, you pick a bullet, maybe by weight based on your twist rate, then by manufacturer. You do your very best to load it so you have the smallest possible SD. Maybe you’re annealing the brass, checking the consistency of the bullet weight, invest in the most expensive powder trickler you can suffer. You put in a ton of effort, trimming, sorting, weighing, and measuring, all to squeeze that extra 1/4” out of the group. Could be it’s not enough, we are still subject to the most mass produced, least controlled item out of the entire system.

The Bullet…

How many times have we seen recalls for lots of bullets ? The multi part manufacturing process is not infallible, thin jackets, inferior lead, melting tips, the microscopic nature of ballistics will exploit any flaw in the process.  We tend to blame other components to our system, but we are starting to see the limitations the bullets put on us.  Most people have no means to explore a bullet problem, but they definitely exist.

Enter the Monolithic Projectile.

This is the only way to make sure each bullet is always the same, using a lathe turned solid. But not all solids are created equal, the materials, designs, and twist rates required separates the good from the bad. I have seen solids do some amazing shooting, and I have seen them never reach the target regardless of how hard we tried.

My history with solids is a long one, I have gone to great lengths to work with them, even using custom made barrels that would not work with anything else. There are certain things I look for, the twist rate necessary, the material used, and of course, the cost. You have to expect at certain amount of latitude when it comes to the cost of solids. The price is not right for everyone, especially when we can stay within our Error Budget using factory ammo. But we can certainly get our monies worth when we want to jump to the next level.

Welcome to the Next Level – Flat Line Projectile

Warner Tools understands solid bullets. They answer all my questions the right way,

  • No Special Twist Rate
  • Copper Material that can Interact with Jacketed Bullets
  • 1 Piece Design
  • Not over doing the weight

This is what we are seeing with the Flat Line Projectiles. We can interchange the Flat Line Projectile with any jacketed bullet without ill effect. You don’t need a special twist rate, most standard twists work within the class. This allows the design, materials, and weight to reach a higher speed. They are not going too heavy, instead letting speed rule the day. Most try to go too heavy which is a mistake. Heavier works but only if you can reach a minimum speed, I get floating them out there, but when the conditions turn sour, that slow moving bullet is not gonna give you the right response. Going to slow effects the BC too.

Speed Wins the Day…

Small SD Numbers were found in every load

The Argument for the 122gr Flat Line Projectile right now over a heavier bullet is the speed. 3100fps is very easy to reach. A mild load with H4350 was over 2900fps, still respectable, and probably a good load for a gas gun, but when you can go over 3100fps, things change. You start to exploit the benefits of using a Flat Line Projectile.

I am not an anal retentive reloader. I think what turned me off, besides the time involved, or the money needed to reduce that time, is the idea of people doing endless load development. Early on, when the matches were spinning up heavy and Sniper’s Hide was a bigger part of that, you’d have members that could never attend a match because of “Load Development”. Seems you read more about the guys fiddling with their load trying to squeeze every millimeter out of it vs taking the time to go out and enjoy shooting. That bothered me, and might have turned me off to the process a bit. But for a solid, or a new bullet I no problem jumping in with both feet.  The consistency of the Flat Line Projectile made it easy.

Prior to starting Josh Kunz of Patriot Valley Arms fed me some starting data. I knew most were using H4350 for their 6.5s. Josh recommended 43gr of Varget, and after visiting Mile High Shooting to pick up some fresh Varget, Adam @MHSA offered up some IMR 4166 to try out.

The Load

Easy to Load with Great downrange results

In order to establish a starting point I used all three powders with some once fired Prime Ammo Brass. I full length sized the brass and cleaned it up. Cleaned up the necks and prepared to drop each.

  • 43gr of Varget
  • 41.5gr of 4166
  • 44gr of H4350
  • OAL – 2.820” for each
  • FED GM210M Primers

With only 25 rounds of 100 loaded, I headed out to the range to give each load a try. Each load was shot over a MagnetoSpeed Chronograph alongside a LabRadar at the same time.

43gr Varget

  • 3147fps
  • SD 8.8fps
  • Accuracy 1.25” @ 100 yards

44gr H4350

  • 2918fps
  • SD 8.0fps
  • Accuracy 3/4” @ 100 yards

41.5gr 4166

  • 3104fps
  • SD 6.5fps
  • Accuracy 1/2” @ 100 yards

I also took the remaining rounds to 800 yards in order to gauge the potential drop at distance.

Average Mils used was 4.0 Mils with a casual zero. I zeroed the rifle with Prime 130gr 6.5CM the handholds were within an inch of center so I just held the difference.

The easy answer rather than play with seating depth was to go with the IMR 4166 load. Based on the initial speed, accuracy and low Standard Deviation, it was the best way to get up and running without using any more of the bullets. So I loaded up 65 of the remaining 75 rounds.

1500 yards – 10.8

1600 yards – 12.0

1778 yards – 14.6 Mils

These were actual impacts on target. We measured an increased Muzzle Velocity of 3122fps with the load. Giving us an SD of 12.5fps across all the shots recorded. Winds were light, switching back and forth from behind and right at 3-5MPH.

This is our baseline for determining the BC for the bullet. Originally we were told Warner Tool had their bullets measured over Doppler. I know this to be true because I was in on that effort. The measured BC was around .635, which is what I used for my TRY DOPE numbers. This was my basic starting point to get me in the ballpark.

Using this BC and the MV of 3100fps, I was going over most of the targets and had to use the data above vs what JBM gave me. Spotting alone can be tough when you drop over the top of target, especially beyond 1000 yards. Lucky for me it has been dry, and I was able to pick up the splash and adjust. Wind was really a Non-Issue, I only used 1.5 Mils at 1 Mile.

Better BCs

recorded dope for the 122gr Bullet

Using the condition above, which are very favorable to long range shooting, we measured the BC for our shots to be .670 G1. I used G1 and the numbers are lining up perfect. I did attempt to get a G7 number and what I came up with is .335 G7. That should work perfect given my conditions.

BCs are subject to the speed and conditions, as well as the rifle used. So this BC is uniquely mine. I believe the Doppler data to be based on a speed of 2900fps. It’s a great starting point, G1 = .635 to .650.   It can depend on your system.

The Flatline Projectile BC often comes into question, but let me assure you, the numbers published by Warner Tool are within 2% of your results at the given average speed. No doubt your results will vary, they will not be off by much. You want to determine your own BC based on your system. By matching the BC used in a ballistic computer to your system the end results will be more accurate.  But the numbers for the Flat Line Projectiles have been very good.

I know the 30 cal bullets were tested, as well as this 6.5 Flatline. So you have a Doppler determined numbers which will be updated shortly.

My range is laid out and measured via the most expensive Vectronix Laser Range Finder available. We have calibrated wind flags, as well,  our experience at this range must be taken into account too. It gives us a great way to measure the values used. These numbers are solid, you can take them to the bank.  My trial numbers all went over the targets, and I used .650 as a G1 BC to start me off.

The Benefits of Monolithic Solids

In all honesty, Solid Bullet are not for everyone. They are for those who want an edge over the next guy. Furthermore they are there to push the envelope. The problem with most solids are the designs, and materials. They can be finicky to load, and often require an aggressive twist range. Consider this, I have a 338 solid that uses a gain twist barrel of 13-5.4, you can’t even use a jacketed bullet behind it. By the same token,  with brass based solids you have to almost dedicate the rifle to just shooting those bullets. Those you see that are  a gold color have a high brass content and don’t mix well with jacketed bullets. You have to clean the barrel completely when moving between a solid and jacketed bullet. This extra effort combined with the higher cost make them less popular.

Solids done right, like the Flatline Projectiles, work in your standard rifles and can be mixed. This is important. The design is not so aggressive as to require a unique twist rate, so you can fill them in between your standard loads. I zeroed with Prime Ammo, and then shot the Flatline Bullets.

Where do I see the 122gr Flat Line Projectile fitting in,

This is an easy question because it does more than you might realize? For sure the competition shooter, the smaller bullet going faster is gonna help you in a PRS type competition. The Speed will not only help with positional shooting, it’s pretty close to what guys are seeing with the 6mm. Over 3100fps with a 122gr bullet you balance that speed with better wind drift vs the much lighter 105. As well if the match has targets beyond 1000 yards you are at a definite advantage.

Into ELR Distances, if you want to explore shooting targets beyond 1000, 1250 yards, etc, here you can do it without needing to invest in a big expensive magnum. The investment in the Flatline Projectile is all you need. If you are traveling to a location that has targets beyond 1000, you are still viable. Supersonic flight for me is beyond 2000 yards. At least 2150 yards, if you are at sea level you are supersonic to 1900 yards. Your 6.5 chambered rifle is now easily 1 mile capable. I hit 4 out of 5 shots at 1778 yards using 14.6 mils. That is insane.

Extend the capability of a gas gun. This bullet like the 160gr .30 Cal Flatline will work in a semi auto. I think the 2900fps load is about perfect to run in a gasser. This will push this rifle to the next level especially if you want to compete with it.

6.5×47 chambering, where this can certainly shine. I find the 6.5×47 to be very good, but most people opt for the 6mm variant, because it fixes the speed problem. Normally with the heavier high bc bullets, the 6.5x47x is slower than it’s more common counterparts. The Warner Tool Flat Line Projectile can get you the speed with a super high BC out of a 122gr bullet.  This projectile in a 6.5×47 would be deadly across the board.  You’ll not only gain that lost 50fps you’ll add to it.

Conclusions – 6.5 Flat Line Projectile

I am super impressed with what Warner Tool and Josh Kunz is doing with the Flat Line Projectile line. They are embracing the technology, have hit on a great design, and are using materials that don’t require you to clean the rifle when switching loads.

Warner Tool Company is well established and is supporting the Flat Line Projectile with data, load information, and supply.

What this did to my 22” AX is nothing short of amazing. I read an article about the 6.5CM replacing the 300WM. Using the right bullet, it’s very easy to see. I know the Facebook crowd like to bag on the 6.5CM but it’s a very good round. It’s accurate, well supported with inexpensive factory match ammo, and it’s being included by most of the big manufacturers. I also understand the price puts this bullet out of the reach for a lot of people. But this is not designed for plinking, you have to put it in the context for it is designed. Precision Rifle shooting is not cheap, this is for guys who understand that and want an edge.

The nice thing, you can shoot a course of fire using standard, jacketed bullets inside 800 yards and then switch to Flatline Solids for every thing beyond. If you determine the difference you can easily do it, and most Ballistic Apps will adjust for the offsets. Zeroing with 130gr Prime 6.5CM ammo, the Flatline was within an Inch. I can work with that.

To illustrate my point, take the Ruger Precision Rifle crowd. For example, the ability to accurately shoot your Ruger Precision Rifle to 1 mile, opens the door for people to understand the skill level necessary to engage targets beyond 1000 yards. Because it’s supersonic it’s not a fight when it comes to wind. It’s predictable in the wind. Sure floating certain rounds into the subsonic region can work, but it’s a less predictable. We want to stay within supersonic flight and at 1778 yards I was still going 1390fps, truly the year of the bullet.

Use Caution when Handloading the numbers I am using may not work in your rifles.
