Vertical Deviations With Powder Charge
David,
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.
