    I think the variances come from reground reamers from over use

    Y'all have a Happy New Year.

    Could be good but finished powder, however, from the previous not having lubricated the patch barrel is dirty more

    An alternative to the use 1,5F 2F which has performed remarkably well
    Note that although the particle size is different, there is practically no difference in speed

    Conclusion: I stubbornly use boots on 65-70 max 80 but I found that for PP it takes so GASSSSSSSSS

    David, I am ver interested in having a mould made up for the hollow based whitworth bullet on the left had side of your photos. I found heaps of these in unfired condition as a kid on the sheep station my late father managed. I remember they bases being quite deep and the skirts thick. There were no base plugs. I think sever hundred paper cartridges had been dumped on the edge of the creek, and I just stumbled upon the bullets by accident at the age of 10 or 12 . Unfortunately none have survived in my possession to date. I reckon it might be a really good bullet to try in my 1st gen PH Volunteer .451, hence the interest

    Kind regards

    Gordon

    A couple of people I know made moulds for similar bullets a few years back and had/have great results from it in Whitworth rifles.

    Pure lead and 100grs of 2Fg? That bullet must upset like putty... I would go for a harder alloy. Then again, I'm not a ML shooter - but my bore-dia. PP bullets in my no.2 musket are 1:16 alloy, and shot over 90 grs of Swiss no.4 (1 1/2Fg) take the rifling, and shoot quite well... No need for pure lead IMO. Also - again with my breechloader and bore-dia. PP bullets - I've found it needs a pretty thick wad to perform best, probqbly helps in avoiding gas cutting of the bullet.

    It's been a long time since I updated my results, since then I've always used 100 grains of 1,5 F Swiss.
    The nipples thank you

    Those Gibbs rifles didn’t set world records for good reason. They will shoot and shoot well , 89-100 grs of Swiss 1.5 Fg was always accurate in mine .It even shot sized down Paul Jones 540 gr. .458” Creedmoor bullets really well. Those Gibbs rifles have barrels made from Mauser steel, rare expensive steel developed by the Germans in the 1930’s to make guns. Not used in America for guns anyway we’re happy with good steel but those Gibbs barrels are special.
