    Searching load data for 338 Lapua using RL 33 and ELD-X 270gr. Alliant and Hornady have not tested that combination. Carbon wrap 24" ,1:9.4 rwist. Anyone tried this combination?

    There is a good reason for this load not being reproduced, it's too slow. Filling this case up to very base of the bullet when seated to spec does not create enough pressure to get this combination up to speed.

    Better powders for this bullet are:

    Re-25
    Norma 217 (very smooth and accurate)
    H-1000
    Ramshot Magnum

    IMR-8133 is being touted as a good powder for cartridges of this size with the heavier bullets. I personally have not found these formulations to be usable for my needs.

    Kind of confirms my suspicions! RL33 supposedly formulated for the 338 Lapua - wondering what that means? I read claims of 3000f/s with 300gr bullet with 33 and don't understand how that is.

    If you can find some of those references I'd like to read them for my own sake. Most of the internet stuff suggests H-1000 or Re-25, at least from what I've seen.

    Here is a sample from Alliant:

    Idk for a 270gr. Too much of a 'tweener weight. Might be a good bullet for H1000 cuz it's a "tweener powder in the 338LM. 7828 might be another good one.

    You should save yourself the trouble and go to a 300gr/Retumbo or a 250gr/7828.

    I used that Alliant data to extrapolate some loads. One load at 94 grains had overlapping holes. Pleased with that but velocity around 2600. Appreciate the feedback - not ready to give up on the eld-x 270gr. Will try some other suggested powders!

    Try Retumbo. I have had good succuss with it and the 270 ELD-X. I don't have my notes handy but I did use a published load.

    Good to hear. I see Hornady does list that powder with the 270gr bullet. Are you getting sub moa and published velocity?

    I’m running 89.5gr RL 26 under the 270s, in Lapua brass. I’m seated out a bit, don’t remember off hand. I also ran 33, was 100gr if I remember correctly. I’ve gotten excellent results outta RL33 and 250’s, 270’s and 300’s. Good luck

    Retumbo availability is diminishing quickly... either they are not making it or a govt contract is purchasing it all. I can't find it in stock any where. I'm likely going to be forced to switch to RL33 or 8133 or something similar.

    This is the same situation most of us have been subjected for the last few years now with powder, brass, bullets and primers. This is the new operational model which component manufacturers are using. Run 'em short, create a situation which promotes hording then lengthen the process times between runs. Voila! Higher prices every time you turn around!:mad:

    As much as I like Retumbo, Re-26 and others in short or non-existent supply, I have been retesting different powders and buying them to replace what the manufacturers won't make available. No choice if I want to stay in business as well as compete.

    True words here. Very frustrating. I'm no conspiracy theorist and I wat to avoid politics here but I bet the govt also has a part in this (the overall goal from the left to disarm us, by slowing making it hard to get gun parts, ammo, etc)
