Indeed. Me too.
Haha. Case neck is lubed before seating the bullet. I have used Neolube
You can see difference on AMP press graph between lubed and not lubed, while on target they printed on the same elevation.

Is this virgin brass? I'll usually lube virgin brass, but after a firing or two the carbon in the necks serves the same purpose for me.
Just looking at the data and not seeing much difference on target and trying to choose which way to go, I'd go with the one showing the better chrono numbers, especially for long distance shooting. Then again. . . I'd still shoot another session to verify.
Except for a couple, looks like some pretty consistent trimming there.

Its pretty obvious to me. When I look at long range groups I am looking at a lot of things. One of them is if its trying to wad up. In your no lube break it down into 3 shot groups. 1 2 and 3 form a nice group so do 4 5 and 6. You can also look at the wad in the middle with one out the left and one out the right. The lubed neck doesnt have as good of consecutive 3 shots or a wad. To me its obvious that the no lube is trying to shoot tighter. I often look at consecutive 3 shots in f class targets. I can tell if the guns trying to shoot, and it takes some of the conditions out that way.

What were your conditions while shooting. It appears that the overall size of the group shot with lube is smaller than the size of the group shot without lube. You may want to retest with no wind or very light winds. The ES of the lubed shots is 1/2 of the non-lubed shots. As asked earlier virgin brass or had it been fired several times, building up carbon in the brasses neck for lubrication?
I'm not sure how any conclusions could really be made either way. Two separate groups at .419moa and .357moa at 900 yards. How can this not be attributed to normal dispersion?
SD's may be half in the second string but doesn't show a positive difference in vertical dispersion as it is also a taller group.
SD's of all shots combined are less than 4.
Amp graph shows what you might think should be a difference, target doesn't seem to agree.
If I was made to make a choice between the 2 and go shoot a match tomorrow, I'd go with the no lube as it would take less time to load ammo. The only real conclusion that can be made, imo, is that is some good shooting and you'll do well with whatever you pick.

Cartridge is 7FCP, shooting 184gr Berger
Lapua brass has 6th firings on them, and this is my test brass.
I totally agree with you 100% on everything you said. For me, the biggest surprise was the AMP graph.
I expected to see a difference on the target, but it's not showing up.
Using Neolube reduces friction between the bullet and the case, and I get that the graph would reflect that. But I thought there would be some elevation issues with bullets seated without the lube.

That is good stuff right there Alex…. Great information… I went to my 1000 yard tuning targets from today and found one rifle wadding up as you describe… I wasnt sure which rifle to take this weekend. Now I am sure.. one shot 3 shot wads…
