Load Data for 147 ELD-M 6.5 Creedmoor

[creedman12]

I picked up a box of factory Hornady 147 ELD-M for my 6.5 Creedmoor to see if it liked them. It did. Multiple groups at roughly 0.5 MOA. So now, I want to attempt hand loading them myself. I've seen alot of folks on here using H4350 so I am definitely going to give that a try. What other powers have you guys had luck with?

if you can use h4350 , imr should be no real difference at least we have used the exact load for both


I love rl 17 it's personally my favorate other than h 100 v but we have been able to use the exact same load for both powders you would just need to do your own work up for safty .

This

44.4gr under the 147eldm's using Alpha large rifle primer brass

Its a significantly compressed load that generates velocity consistently around 2700 for me and is accurate

In a case with higher volume internally you'll need to work up a different load and it may not be quite so compressed but thats as high as I go with the large primer alpha brass without signs of significant pressure/flattened primers

I figure I'll bring this thread back up as I will be loading the 147's in my 6.5 Creedmoor. Has anyone developed a load with Varget or H4895? I'm in Northern NM and need a bit more temperature stable powder than H4350. Temps can range from 50 F in the morning to over 90 F in the afternoon during the summer or between 20-70 F in the winter. It can be worse when you're in direct sun light.

I see OAL is 2.800 as stated by Hogdon's load with H4350 . Just curious if anyone has used a bit more temp stable powder.

H4350 is as temperature stable as anything out there and goes with 6.5CM perfectly.

Does the 147 seat deep enough in the case that it looses powder capacity? Or if you seat it long enough so the seal ring/bt is at neck shoulder junction will it still fit in short action magazine?

I usually do a bullet seating depth test starting at max magazine length and working in backwards in 6/1000 intervals. Case capacity is never an issue unless using slower powders like H4831 or RL26 then you might get some light compression but completely safe.

H4350 for me only yielded a difference of 10-12 fps from 5 degrees to 70.

Thanks for the replies. I was doing a bit more reading and saw a good article comparing H4350, Varget and two IMR powders for temp stability. I didn't realize H4350 was also part of Hogdon's Extreme line of powders for temp stability. The results showed only 0.2 ft/s change for every deg F while Varget was about 0.4 ft/s per deg F.

Would still like to know if anyone has load data for Varget or H4895 as I have a lot more of those powders and it's nice to keep the number of different powders down a bit.

All the "Hogdon" powders you mentioned are ADI temp stable powders, the 2208 and 2206 (Varget and H4895) are really too fast for heavies in the creedmoor, low case fill and velocities for the same peak pressures. If you wanted to step one powder away in ADI/HOGDON you would go to the slower 2213SC as mentioned above to a likely compressed load.
