Who Shoots, Casts and Loads for the .455 Revolver?

Was successful downloading on my second attempt.   Seems that my anti-virus interpreted the Lockbox opening page asking me to logon or create an account as a phishing site.  I was eventually able to bypass this and download finally. The article is good as far as what it covers, but does so in less detail than what I've put together.   I am glad to see that our load data is in agreement and that I independently came to the same conclusions that he did. But I think my concentration on the modern Accurate molds is more constructive than trying to use the inferior design antique traditional bullets.   Also, my observations with two Webleys both having tight cylinder throats smaller than barrel groove diameter, and also tighter bores than either Colt or S&W .455 revolvers of the period is noteworthy, and warrants further discussion, which I will now add to my draft.  People who load based upon what they read are liable to use oversized bullets which will run pressure up, and while soft hollow-based bullets will tolerate being squeezed through tight throats and will slug up again to take the rifling of a larger barrel, doing so is NOT the best technical solution. Being able to show results before and after cylinder reaming of my Mk VI should be interesting, and I am confident now that reaming the cylinder throats from their original random .449-.453 to a uniform .4555” all the way around, and having new Accurate molds cut which drop .4545” bullets, allowing for growth from age hardening during long term storage, was the correct approach. I also have full confidence that using 3.5 grains of Bullseye with bullets from 240-260 grains, specifically Accurate 45-240H1 and 45-259H is a more useful approximation of original service velocity, with a superior modern long, flat-nosed bullet.
