    More LAPUA Naturalis 140 gr testing

    I was testing a bolt 6.5 Creedmoor and a Howa bolt 6.5 Grendel.
    Thought I'd post both results.

    Sea level. 92deg F

    6.5 Creedmoor Ruger Precision rifle
    LAPUA NATURALIS lead free 140 gr
    H 4350 powder
    federal 210 m primers

    Measured velocity using a Magnetospeed.

    40.5 grs 2636 fps
    41.0 grs 2665 fps
    41.5 grs 2667 fps
    42.0 grs 2712 fps Retrieved
    42.5 grs 2732 fps Retrieved
    43.0 grs 2754 fps Retrieved

    The 3 bullets in the photos are the last 3 fired. Expansion was good. Bullets stayed together well.

    6.5 Grendel Howa heavy barrel
    LAPUA Naturalis 140 gr
    CCI 450 primers
    LAPUA brass
    CFE powder

    I was a little hesitant to go too high with no published data and CFE being what it is.
    There were no pressure signs at all.
    I did not retrieve any of these bullets.

    26.5 gr 2086. fps
    27.0 gr 2108. fps
    27.5 gr 2150. fps
    28.0 gr 2209. fps
    28.5 gr 2227. fps
    29.0 gr 2276. fps

    A 13" square piece of Cypruss.
    Very coincidentally all 3 barely made it through after expanding and were just setting there on the far edge.

    Shot a little more out of my Howa grendel with the Naturalis today. Only went up in 0.3 grain increments using my Magnetospeed again. No pressure signs at all. No flattening of primers or erratic velocities.

    I began at 29.0 gr where I finished the last time.

    29.0 gr 2269 fps
    29.3 gr 2287 fps
    29.6 gr 2309 fps
    29.9 gr 2329 fps

    This maybe where I stop for now unless a powder manufacture comes up with some "bolt" gun load data.

    ANYONE READING THIS PLEASE BE ULTRA CAREFUL. THIS IS A BOLT GUN AND NOT AN AR15. THERE IS A LOT OF BEARING SURFACE ON THIS BULLET THAT CAN CAUSE EXTREME PRESSURE.
