    Better yet, just get a Saeco 645 mould and go.

    with the proviso that dynamic stability cannot be calculated like gyroscopic stability.
    if you can do it in a lathe, it might pay to shorten some that way for firing tests prior to spending money.
    keep safe,

    gotcha - thanks - yes its 18 twist - yes can do in the lathe . That boolit is 550grain and I didnt want to go that heavy in my 76. CBE make decent molds and can get that one reasonable price - still nutting this stuff out. lots of good info coming forward here and my thanks to all for that

    Thanks ---- was looking at the Saeco 745 - they both look ok to me - litle more lube than some of the others maybe? - searched around some and both these out of stock where I looked.
    Changed my range around today so got a bit more opportunity to test stuff - still playing with that LEE and it seems like wind is the issue.
    cheers and thanks

    i started using a led sled for 200yd load testing, and i believe it's helped. wind, if present, is the only real bugaboo.

    That 645 bullet carries plenty of lube, and it shoots well to 1000 yards from 45-70's. If I were to limit to one greaser in the 2.1 case that 645 would be my choice.

    Shot again today - I guess we might call it dis proving the 500grain LEE !
    I have two versions of that mold they a little different shape at the nose - thought that might make some difference - the wide base band old version is what I have shot most and it has seemed ok - there was a bit of wind today - I already had my elevation setting so I let one go - got a hit - shot four more - went to investigate (this is 500yards and my scope is just not that good) anyhow the group is dead on for elevation but far right of the target - its ten inches high by seven inches wide, two are keyholed bad a third is definitely wobbly and a fourth the hole is not quite round - so we obviously have serious instability but from the look of it only in the last fifty yards or so ?
    So finally that has kinda made the point - I returned to fire five of the later version of that same mold - these boolits 15 grains lighter, same powder, same lube, same everything and from the look of the strikes they make a half reasonable group - BUT about four feet lower (on the ground in front of the target) still trying to figure that one out - the strikes were in line with the hits on the target with the other boolit - no sight change ??????????????? (something must have shifted there that I havent figured yet)
    Along the way I also tried the Lyman 490 grain Snover my mate gave me ten of - all over the place!!! I did manage to fell a small branch from a grey gum tree overhead at the 300yard mark - that was kinda fun.
    So at this point the saeco mold looks my best move - I want something with enough lube that I can shoot with the blow tube. While I wait I might put a few of those LEE boolits through the lathe and shorten the nose some - it might be interesting to figure just what is the problem.
    anyway thanks for the advice
    Joe
