Another good to see you around again Recluse.....
I came from a small community and I knew two guys that reloaded. They reloaded for their rifles. I reloaded with them for a season then bought my own equipment, a Rockchucker and a few case prep tools.
My first manual was a Speer #9 the latest at the time, actually it was hot off the press. The year it published was the year after I started reloading with my two buddies. If I remember 74 was the publish date. I started reloading in 73.
I do believe I pretty much wore that manual out. I still have it and use it for comparison but the hard cover is in bad shape.
I have a number of manuals up to the latest Lyman. I mostly use them now for the charge tables. And since ole Al invented the internet, I go to the powder manufactures web site and look at the load data there.
When I am working on a new load which is seldom now. I'll break out at least three manuals and start comparing load data for the load that I am working with.
It does appear the manuals are going more lawyer friendly comparing powder charges listed 40+ yrs ago all the way up to current manuals.
I'm also aware that some powders have changed some through the years as well so I do pay closer attention to the load data in the newer manuals to start working up a load.
