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.

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.
