So I have been lurking for a while now, I have made a few posts here and there, but nothing with much contribution yet. Now it is time to put up some meaningful data for all of you. I have noticed it can be hard to find load data on the Hornady 147 Gr ELD-M for the 6.5 Creedmoor. So I did some research and bought a few powders that interested me for this. I chose 4 different powders, loaded up 50 rounds of each, took it to the range and here are the results for anyone who is interested.





The powders I tested were RL16, RL26, H4831 SC, H4350. After testing all four I had great results with all of the in different ways. I will let you all be the judge of what might work for you. This data will hopefully help anyone trying to choose a good powder for the 147 ELD-M.



Use Caution when using any of these loads, be sure start low and work your way up. All these loads below, start high and get over recommended charges. Don't be a fool and blow up your tool.

After doing these tests I thought I would have a clear winner but now I just want to test these all more thoroughly. So this test has turned into phase 1 now. I will see what kind of fine tuning I can do to these in the future. I will keep you all posted when phase 2 is completed and I will post the results for you all.

    There is a lot going on here:

    RL16 - You went about 1 grain over max, you had an major POI shift at 41.8g, that is the beginning of optimal pressure for this combo.

    RL26 - You went approximately 2 grains over with this powder, POI stayed consistent for all groups even though pressure was probably around 70,000+ PSI. This powder is a winner.

    H4831SC - For some reason you didn't get to max pressure with this load (46g according to Hodgdon), but again POI was consistent, another possible winner.

    H4350 - 1 grain over max, major POI shift at 41.5, this is where optimal pressure starts.

    When doing this type of testing, group sizes mean nothing. That can be adjusted with seating depth. What you are looking for is pressure and POI shifts.
    Hope this helps.

    I agree completely, I was very happy with the results of the text I think that 4831sc produced the best groups, but H4350 gave me the best SD and ES. By far the best velocity was from the RL26. I am going to be doing another test and I will be playing with seating dept. I would really love to find a group that shoots low ES with the RL26

    I would really be interested in seeing how H4831SC does until you hit pressure versus H4350. The velocity and accuracy between these two powders always intrigues me.

    I'm glad you got some data with h4831sc, as that's what I'm toying with since I find it more often than h4350. I love it personally, and am currently testing in my savage with a Shilen. I would rather potentially sacrifice barrel life with this powder vs h4350.

    Thanks for the info. Just loaded up some rl 26 as well. Been using 4350 and hope to find a good load by switching. Like the speed from rl26.

    Here's some results from a 24" Tikka T3x CTR. I started buying H4831sc when H4350 was so scarce, and have now standardized on it for PRS loads. Although the H4350 gave me some good groups with low SD, 45.2g of H4831sc and the 142g SMK's was a sweet spot.

    I found my tikka t3x superlite liked rl26 with 47.9 with the 147eld -m .005" off the lands. This superlite 24" light profile barrel has been hard to load for. This combination is producing 1/2 moa groups. I wasn't able to get the higher velocity and accuracy with h4350. I was getting to the point of giving up on this gun for acceptable accuracy for a hunting rig til I found this combination. My CTR is much more accurate and easier to load for.

    This was with starline large primer brass and cci 250 primers. No pressure signs or primer issues. No stiff bolt lift. I have a new lab radar on the way for my next range trip to measure velocities and confirm ballistics.

    I was getting discouraged with my initial groups, considering how well my other Creedmoor was doing with various loads, but that 45.2g of 4831sc was a sweetspot, been using it ever since.

    I am running the exact barrel and bullets but my barrel has a 1 in 7.5 twist.
    Any suggestions for the loads for this setup?

    I would try the same work up. I don't think the twist will will affect your pressure while working up charge weights. It may affect you downrange performance though.

    Thanks!
    I have used the H4350 before but it's nowhere to be found now. I'm going to try the RL26.
    140+ weight bullets and you should have a node in the 46-47 grain range.

    I run my 142 matchkings with 46.9-47 of R26 inside Prime brass with Fed210M primers. Hammers.

    RL26 is very hard for me to find right now. In the end I went with the reloder 16. Gave me the lowest es/sd in most temps. More important for me being in Canada with such huge temp changes through the year.

    Just did a pressure test with 147's and RL26 today in my factory Savage 10 - 24" barrel.

    Got to 47.5 and didn't really have anything on the case that'd concern me pressure wise... I just can't stuff anymore powder in the damn case lol

    At 47.2 and 47.5 I got 2836fps for both.

    Going to try 47.3 and see how it groups and how ES looks.

    If I could push 147's at 2830 on regular basis that'd be pretty legit.
