I just found a website with quite a few online handloading references (plus much, much more).
Cheaper Than Dirt - America's Ultimate Shooting Sports Discounter
on seeing the preview of this post - the above link goes to the library - if anyone would prefer to type it in its cheaperthandirtguns (not just cheaperthandirt) - with www. in front and .com at end, then add "/library" to the end
Rule 3 posted the "Table of CCI Primer Energy" in another thread and well I read the text above the chart and got curious as to the source. Searched it and found it in Speer Manual for Reloading Ammunition No. 7". They actually have the whole book online. Interesting read for me, I have mostly Lyman books, just spent a few hours reading the upfront stuff.
Anyway, couldn't quickly find the link on their page to see if they had other books, so I just shortened the URL to the address above and found a bunch of categories. Under the handloading of ammuntion section are a bunch of other references. I'm interested in
Principles & Practice of Loading Ammunition, by Earl Naramore for now.
Lots of interesting topics - old books - thought I'd share. HAVE FUN!!!!
