Is there a sweet spot for loading these? I loaded a few different lengths and they didn’t shoot well. I started .050” off the lands and went from there. Do they prefer to be seated closer to the lands?

I didn't mess much with them . this is the only target I can find that I saved . this would be from a 260 rem . by the looks of this target you want to go closer .

You should try Berger's VLD seating test to find your seating. I would start at the minimum powder load for your given powder and run the VLD test to find the correct seating. I did one two weekends ago for a Bergara B14 HMR in 7mm Rem Mag, followed the recommended seating depth for Hunting and found the seating depth the rifle likes at .050 off the lands. Now I am in the process of fine tuning it to see if it can improve from .550 4 shot group. Give it a try, it should work for you.

I start all my loads the same way no matter what projectile it is.
And that is at 10thou off the lands, I go through the charge range & find the best group.
I then change the CBTO to 5thou, 15th & 20thou.
I have never had to go any further/deeper into the case before finding the right depth, even with Berger VLD's.

I’m seating the 162 ELD-X .060 off the lands in my Tikka T3X 7mm Rem Mag. Getting .4 to .7 3 shot groups with H4831. Still working on it.

I have mine seated at .050, shoots .7 three shot group but that's the longest that will fit in the magazine box. Older savage 111, ADG brass, 66.5 grains Retumbo, 2980fps. I still working on my load.

I’m my 7RM I have them really close to the lands for best results, but a mate found his 7mm08 liked them about .150” off the lands. Suck it n see...

.065 was the sweet spot for me.

Don't know about the 7mm, but the 6.5s in my PRC like 20 off and closer.

I have been shooting these bullets in my sons 6.5/284 as well 300 wsm for hunting. My wsm seems to like them about 10 off. The 6.5 seems to be just about touching. I don’t have a photo of the eldx groups that we have shot but the group that I am showing a photo of is a 5 shot group that my son shot off a bipod at 100 yds. I can say this that the 143 eldx shoots nearly the same. Last year before we went out west my son had his 6.5/284 at the 1000 yd club and shot it off the bench with a bipod and rear bag and he busted a clay bird at approximately 1034 yds on the first shot and then he went to a paper target at 1000 yds and shot 1 shot and was 4” left of the x ring.

Nightforce has great tracking capabilities, they are rugged, a bunch of elevation, holds zero forever, and reticles are designed for long range shooting. So if you are looking to shoot long distances constantly, then you need a scope that can take the abuse. -- gilmillan1

The total package. Nightforce is the best I have used as far as turret feel and solid detents. I have never had one that didn't track right on and always return to zero. Nightforce NXS is the best value for everything I need. -- Broz
