Many of us have noticed the performance drop in more recent editions of manuals, for example the 220 swift being loaded in most modern books to similar velocity as the 22-250.
What are some of your favorite go-to manuals for older hotter loads?
I have manuals from several sources dating back to the 60's. However I don't load "hot". There is a reason some loads have been reduced in the newer manuals. If you can't achieve the velocity you want with current data, switch to a cartridge with more powder capacity.
