I also compare everything in recent print that I can get my hands on, as well as the online info from powder companies. I keep Nosler, Barnes, Hornady, Speer and Sierra manuals at home, and pick up the freebies from the powder companies as well. I very often refer to the online info from Hodgdon/IMR/Winchester, Accurate/Ramshot, Alliant, and VV.

If I use online reloading info from places like here, loaddata, reloader's nest, etc., etc., I compare it to the above sources and proceed with caution, using the chrono.

I keep the freebie manuals from the powder manufacturers because sometimes they have good info on powders or cartridges that newer sources have deleted and/or discontinued.

Bring enough gun and know how to use it.

Know that it is not the knowing, nor the talking, nor the reading man, but the doing man, that at last will be found the happiest man. - Thomas Brooks (1608-1680)
