    Does anyone know what speed to stay away from with the 180 ELD-M’s so they don’t blow up?

    I’ll soon be loading for one once my barrel comes in. 9 twist 26” straight, I only have h4350. From what I’ve read in the Aussie forums, people have been loading around 56g of AR2209/H4350 with them still being fine.
    With a 1-8 I downloaded them to 2800 and still had a few pop.

    Damn!
    These 183 SMK’s are longer than my 190LRHT!
    They are in the lands at 3.122 vs 3.099 for the 190’s.
    Be inside to see what the BC works out as.

    When I measured mine in my 7mm saum the 183 was 3.115 But thank you for the info I needed to know the difference So if I do my special throat it wasn't too long for the either of them. They claiming .377 for agverage

    My barrel has a fair among shots in it now.
    the throat has definitely moved forward.

    We’ll see if they are as consistent as the Berger.

    I’m suspicious.
    Yeah irs my buddies barrel our local gunsmith has the reamer and does alot of work for us and is a great guy i might have to double check with him. Might just be .090 like yours. The 170 pva bullets are 3.230

    Finally! New barrel in house.
    76 cm of unicorn steel (at least for us in Norway.) It`s a Bartlein 1-7.7" twist 5R.
    Chambered in 7 mm Blaser Magnum. So far I have only tested 190 gr A-tip with N570 and Fed 215.

    Results:
    69,0gr avg 911 m/s = 2989 fps
    69,5gr avg 925 m/s = 3034 fps
    70,0gr avg 934 m/s = 3064 fps
    70,5gr avg 946 m/s = 3103 fps
    71,0gr avg 951 m/s = 3120 fps

    And the good news is that all bullets made it to the target!!!

    I don`t intend to shoot the loads this hot, but rather provoke the Hornadys to breaking point. And so far they hold up well and groupings are around 1/2 moa. SD /ES are a bit high, so I`ll try another powder to see if there is improvement. N570 is great for getting speed up in a long barrel, but it is really dirty.

    I did but it was foggy that day and I couldn’t get past 800 yards.
    They had no trouble hitting steel though.

    Well that is always good. I think tuesday im going to try and get a load going with them and test at 900. If all goes as planned
    I got a new barrel coming and from the little I saw I’m glad I bought a bunch of the 183’s.
