H-1000
RL 25
Those are the only powders I have tried as per recommended on both this sight and the LRH sight. I have use both when working up loads with the few 338 LM's I have tried. I have a 338 EDGE and started with H1000. Groups are around 1/3 MOA with the bi pod, so, with prices as they are and components in short supply, I quit testing.

It was, by far, the quickest and easiest load development I have ever done!! I am sure that the 1/4 MOA load is out there, but that last 1/4 MOA is sure expensive!!!

Hunt up some RL-33 if you can..... I know it woke up a few of my 338Ultra Mags..

VV N560 is good

VV N570, work's extremely well and less then 20 fps ES all day long and all year long. I couldn't believe it myself, even borrowed a shooting buddy chronograph to compare against my chronograph, they both were within 2 fps of each other.

+1 for N570. I'm helping a buddy who is new to reloading work up loads for his 338 LM. We have not chrony'ed them yet but N570 has won the accuracy tests hands down. Way better than anything else we've tried. He is shooting 300 gr scenars if that matters.

N570 and 250 scenar has been my load , VERY consistent load. I tried H1000 with good results but not as good as N570, I also noticed the N570 recoil was less.

I use RL 22. Still shoots 1/2 moa and better with over 1200 rounds down the tube with 300 gr SMK's. Scott
