    Vertical Deviations With Powder Charge

    Thank you for your recent free for download, Journal. Being a LR shooter, I've been reading your current article on "Powder Charge Experiments". It supports what we have known about early shooters using larger powder charges back then from 100 grs to even more powder. I'm having a tough time interpreting the measured deviations in the article. What do you think it means when it is printed as 8 80-100 in. or 11 68-100 in.? All the tests used 1F Hazard. The Sharps Rifle Co. recommended a similar charge of Laflin and Rand or Oriental powder. It would be interesting to know where these powders fall in comparison to Swiss 1-1/2. Being a GG shooter, I'm using between 84-6 gr of Swiss 1 1/2. Maybe I should try some 1F?? Only the PP shooters can get that much powder in their cases. Seems as we get older, we are all shooting lesser charges than they did back then. Also read yesterday that the Sharps Catalog listed their 550 grain bullet as being 1 13/32" long or about 1.40". Shorter than what I thought was around 1.5".
    Your article was printed in 1875, just one year after the first Creedmoor match. I wonder how much influence this article had on what the shooters did back then.
    Just rambling here but once again, thanks for all your great work and enthusiasm.

    Well, 8 80-100 in. I interpret as 8 80/100 inch or 8 4/5 inch. I'd assumed the fractions of an inch had all been expressed as 100th to enable easier direct comparison, avoiding some mental gymnastics. The article gives some bullet detail, but just refers to with or without lubricant - it feels like we only have half the detail of the cartridge loading. I wonder what wads / lubricant were used. Wingate in his 'Manual for Rifle Practice' (I have the 6th edition of 1878) notes, "the tendency is toward heavier charges; and all the American team of 1875 used from 100 grains to 108 grains, and considered that it gave them an advantage, their bullets being less affected by wind than those of their opponents." I have an original pack of Sharps bullets, and these (measured wrapped) are 1.5" long.

    David, I notice that the Sharps 550 grain bullets were made by Winchester. Here is a picture from an 1878 Sharps catalog that states that their 550 grain bullet was 1-13/32" long. Could nose shape have made the difference or do you suspect that the Sharps catalog is wrong? The picture doesn't show the nose of that bullet so maybe it has a meplat but I'm thinking it is their LR load.

    We’re only talking 3/32” (or approx .1”) between my bullets and the those in the catalogue. Mine were measured over the paper patch too, so there’s the paper thickness over the base included as well. Not sure of the date of mine and the time line of any changes that may have occurred in bullet design.
