    Cast 70, 5% tin, all came out at .367.5/.368.
    42 came in at +/- .2 grain, averaging 199 grains, the rest will go back in the pot.
    Hitek coated and loaded 18, 20, 22, 24 & 26 grains BM2 (3031 equivalent).
    If this wind eases off tomorrow them I'll see how she goes.

    Well D day arrived.
    Was a bit nervous due to a couple of reasons.

    Had I wasted $2500 on a gun that won't shoot.
    Will I blow myself up.

    Range was 40m.
    100m next time.
    First 2 groups were 4 shots, the rest 3.
    A bit of unburnt powder residue left but that didn't seem to affect accuracy.
    Federal LRP, 199gn accurate mould, hitek coated, unsized.
    BM2 (3031 equivalent) 18, 20, 22, 24 & 26 grains.
    Holy cow this thing shoots pretty **** well.
    Who would've thought a 106 year old gun could shoot this well.
    Sights weren't touched.
    Will put them over my chrony soon.
    No leading evident.

    Wow, that was realy good news!
    Great shooting!
    What velocity do you think you are at?
    Using any filler in the case?

    Well I was a bit premature in my celebrations.
    Moved the target out to 100 metres and this is the best I got.
    24 grains gave around 1440 fps over my chrony but a deviation of around 40 fps over 5 shots.
    No filler, should I be using filler?
    I've loaded up another batch for tomorrow if the wind holds off and will move the target to 50 metres.
    Will be trying 26, 27, 28 & 29 grains.

    Tried 26, 27, 28 & 29 grains BM2 at 50m.
    26gns average 1513 fps
    27gns average 1575 fps
    28 gns average 1607 fps
    29 gns average 1669 fps

    28 gns showed some initial promise with 2 holes touching then it went haywire from there.

    Next step is using polenta as a filler and start at 22grains, after that I'll up the tin level to maybe 7.5% from 5%.
    FYI the bullet mould is a GC mold so that is an option but Im not really pushing those sorts of velocities.
    Still open to suggestions.

    For the 9.3 X 72R I think you need another couple hundred feet velocity. At 100 you could be too slow. As far as I know the standard load was around 1900 fps with an approximately 200 gr. bullet. As far as your alloy I'd stay close to Lyman #2 or softer.

    The learning curve continues.
    Loaded 20, 21, 22 & 23gns Bm2 under polenta.
    Polenta and the chrony don't get on as seen below. Nfi why I didn't take a pic of the 22gn load.
    Moved the chrony out to 2 metres on the 23gn group.
    Next step in 18 & 19gns BM2 under polenta.
    Adding polenta has increased fps drastically based on some of the ones that registered over the chrony.
    First pic is 20gns fyi.

    20gn, 904, 900, 1639, 1500, 2183

    21gns, 1725, 2000, 1709, 1512, 1642

    22gns, 1605, 1438, 420, Error, Error

    23gns, 241, 1316, 1341, 1334, 1309

    An update for those following this thread.
    I think I've found THE load.
    FYI the black circles are around 2 inchs.

    19gns BM2 + 29gns Polenta (48gn case capacity with slight compression).

    1st pic- 6 oclock hold on circle, 18gns + 30gns polenta at 50m, not so flash.

    2nd pic-Holding on black mark at bottom of A4 target, 19gns + 29gns polenta 3 shot group at 50m (2 dud primers).

    3rd pic-Holding on black mark at bottom of A4 target, 19gns + 29gns polenta at 50m.

    4th pic-6 oclock hold, 19gns + 29gns polenta at 75m.
