70.0 H-1000 was max in mine with the 175 eld-x.
I ran it up to 71.0 at 3086fps but that was a bit too warm.
27" brux 9 twist, it shot a little over 3000 fps and 1/2" with 70.0
I don't remember the the length, but it was throated out quite a bit.
.060 off barely fits in the mag, but lucky for me that's where it liked to shoot, which is pretty much what I've been seeing with the eld-x. .050-.080 off is where I always end up with these.
67.0 and .050 off seems like a good place to start.

I haven't forgot about this thread guys, I just haven't been able to make it to the range. The range is only open Saturdays and Sundays, and I've been working weekends. I would go out into the woods and shoot, but there's a fire ban right now that prevents me from doing so. I have the ammo loaded and ready to go, I'm just patiently waiting. I'll update once I can. I loaded up 25 rounds starting at 65 grains of H1000, going up .2 grains at a time, finishing at 70 grains. I'm going to attempt to do the Satterlee load development method. Hopefully I'll find both a good starting point with this method, and my max powder charge at the same time. Sorry so long, but I'm hoping next weekend my boss will let me enjoy Memorial day weekend outside of work.

Ok, I finally made it to the shooting range. I have to say that I'm very pleased with the new rifle and the load so far. I bore sighted the rifle at the range, and hit the the bottom right of the target with my first round. I dialed up and over, and put the second round just left of 2 inches high at 100 (the shooting range I went to only has a 100 yard range). I dialed it over again and fired the remaining rounds. In total I fired 14 rounds. I started at 65 grains of H1000 and ended at 67.6 grains. I had loaded up all the way up to 69, but I started to loose my rounded edge on my primers at 67.6 grains. I know that I could have continued on, but I was already at 3000+ fps, and I want to get decent brass life with this load. So I stopped right there. Here is the pictures of the chronograph readings.

So in the end the main group on the target contains 12 rounds in it. I had very good horizontal stringing, and the vertical stringing is to be expected with the varying charge weights. I'm going to now load up a few loads in the 2950 fps group, and a few in the 3000 fps group, and see which one shines at a much further distance. I think for the most part I've got the seating depth just right (.030" off the lands).

I don't know how you find an accuracy node with a 100 yard ladder test. Hard to see barrel harmonics with a single group of 12 bullets in one long tear. I don't go by speeds alone.

Have you tried or researched the Satterlee method? It works great for me. I agree that shooting further than 100 yards would be ideal, but the mountains are shut down right now, and the furthest shooting range we have that is open is 100 yards. You can still get valuable info shooting over the chronograph and the Satterlee method though.

I know the Saterlee method. But, I never shoot the test at 100 yards. You not only have to look for velocity flat spots, but for barrel harmonic nodes as well. Meaning very little vertical separation between a group of 3-4 consecutive shots @ 400 yards.

I agree. I would normally shoot much further, but the mountains are closed due to fire restrictions here in AZ where I live. And the only shooting range I have access to, only has a 100 yard range unfortunately.

Ha! I am in AZ too. I feel your pain for shooting distances right now. Hopefully monsoons will kick in soon.

Nice. Yeah I hope it starts raining soon. The forecast looks promising, but I won't believe it til I see it.

It finally rained, and I made it out to shoot my rifle. I'm super pleased with the results. I zeroed at 200, ran my info through my Applied Ballistics app. I then ran straight out to 500 yards, and fired 11 rounds. The group measured just over 2 inches. I'm pretty pleased to say the least. This was off my bipod and a rear bag, from the prone position. I'd say I have a winner. I settled on the 66.8 gr load.

I'll be honest, this is the best group of 5+ rounds I've ever fired at 500 yards. I chalk it up to no wind that morning, and a lot of luck. Lol.
