pretty sure the Warner Tool folks are presenting BCs that they have verified in the field at well past a mile. You might want to contact Josh and/or the Warner's.

Nice looking group and MV! Good luck with your load.

I have run them to 1,900 yards at 3,100 fps, and the G7 BC is right on the numbers.

Thanks guys! Good to hear, I will hopefully test them at 2k this week or next. California is flooded so spotting a miss is going to be interesting in the mud

On the other hand, my experience has been that they make a much smaller signature on steel than conventional jacketed projectiles, making it that much more important to have a camera system in place when shooting ELR distances.

Agreed, the mark on steel is pretty small, as compared with a jacketed pill.

Thumbs up lash...

But the small watermark on the steel is really a small part. It is mainly the lack of frag from the hits that presents the most challenges. The ploom from the frag of a traditional, provides solid hit signatures and more importantly great at target wind speed information, even better than a miss.

That said, the 256 has a small bearing surface, leaves extra room in the case and so it runs fast. Plus it is easy to load for, makes small groups and has a real world great BC..

Still find myself switching between the 256 and the 285 Amax

Diver, funny that you mention the 285s also. They are my favorite every day projectile for my .338. The Flatlines are awesome for ELR, but inside of a mile I like 285s all day long.

Only small issue that I have is that my barrel is funky and I have to clean and 'season' it before switching to the Flatlines. If I don't, I'll waste 10 rounds or so before it settles down to shooting awesome again. That's a bit much cabbage to fling down range without worthy results, so I don't switch back and forth between them much.
I know that not everyone has this issue and it may be due to the button rifling on my stock barrel. I'm not sure.

One more to think about as well ALL get crazed about good solids. In my opinion, having put a lot of solid rounds thru 224, 243/6mm, 6.5, 284/7mm, 30 and up; there is a limit to the balance of BC gains and usability, hunting aside.

Most of my hunting is non-lead mandate, so I have been forced to use them for sometime. Once the mass of the solid drops below 130 grains, practice or matches on steel really sucks.... match results can suffer; did the hit get scored?

Anyway, my point is that I think 30 cal, or super fast 7s are still ok, but the 100 grain 6's etc in development are going to find a deminishing ROI for steel matches.

That said, I am ready to develope a load and use the 6.5 flatline when released.. These guys did a very good job to date... and really push other top solid makers of the top of the podium.

you said you have to use them for hunting? How do they do? Ive considered them for only target use so i was torn if i would use them. If they do ok I could use them in a pinch

The phenomenon of degraded accuracy when switching from jacketed to solid bullets is quite common. 20+ years ago most guys were using monolithic brass bullets in the FCSA .50 ca matches, but found if they tried to switch to a 750 AMAX, or visa versa they had to completely scrub the barrel clean before it would settle down and shoot well again.

Was this due to the high zinc proportion in the brass? I've read that the WT Flatlines are good to go and don't require any special cleaning to maintain accuracy when switching from solids to copper jacketed lead projectiles

Everyone saw Frank killing it with the 122 gr flatlines. I doubt he had to do any scrubbing or anything else to get them to shoot. Josh hasn't mentioned anything to me about having too. He uses them mid match on longer range stages so theres no way they are terribly affected by the barrel having jacketed bullets go down it.

I cannot attest to the 122 6.5 flatlines, but I have found that in my .338 barrel (26" Savage 110 FCP stock factory, for reference), the 256's did take some "seasoning" before it settled in, but now shoots consistently. I was switching back and forth from Hornady 285s to the Flatline 256's and was having problems with the Flatlines and consistency on target. Upon the suggestion of Dan Warner, I stopped shooting conventional projectiles in this barrel and focused on just the Flatlines and am having great results. I did do a basic cleaning, but there was no scrubbing, nor did I use a copper cleaner. Just Hoppes #9; two wet patches and two dry patches.

Understand that my focused application is 1 mile plus in Florida, and so is maybe different than the application for 122s's in a PRS match situation.

I swap the 151 7mm and Berger 180s in my 7WSM without issues.

Our experience with Flat Lines, it started out with using the 256s in the 338 LM we had seen some very impressive speeds and accuracy with this combination but the 338LM got put away due to a 375 Snipetac and 375 VM2 builds and RnD.

We were very impressed with what we seen prior and our goal was to use the 361 gr. Flat line in the 375s - to gain a balance of attainable speed with a high BC bullet versus High BC and mass.

Our goal was to have a load that was
Accurate with very low ESs
User freindly on Brass
Loaded to handle the 90 to 100 degree weather without pressure issues

The 375 VM2 got parked and was a backup rifle
The 375 Snipetac was our primary focus

We ended up with a load running a easy 3028 fps with low single digits ESs able to handle the high weather temps. We were very happy with the preformance of the bullet and it is our go to bullet to this day.


At the 2017 King of 2 Mile the 361 Flat Line was the only bullet that busted up the paint on all of the qualifier targets including the 1660 yard Cold Bore after the two days of qualifying.

On the 1990 yard target we held an estimated 10 to 13" vertical on the 3 rounds fired. Very nice when dealing with the wind given to you while on a time restraint and under pressure.

Thanks Dan, Alan and Josh for a great product.


The 32" 9 twist running at a easy 3028 fps combined with a 80 MOA rail and the Vortex Razor Gen II MRAD easily gave us the capabilities to aim at the intended targets and still be able to dial down use the system and hit a 1" dot at 100 yards if asked.


We are looking foward to a even more exciting and productive year shooting in 2018 with the Warner products!



Shown above if the picture works is a Flat Line 361 gr. Recovered at a steel plate at 3040 yards while in Colorado prior to arriving at the 2017 King of 2 Mile - Still showing some good authority at 3040 yards hitting steel.
