[Dubious]

I use the published nosler manual as a base line I then look on the hodgdon site to cross reference I also sometimes email either the powder manufacturer or the bullet manufacturer if I'm looking for something more specific. I find the manufactures are generally quite speedy with responses. If you're doing any sort of wildcatting no-one wants to Give much data other than use the parent case loads (25-06 to 26-06AI or what have you) as a baseline and work up. Reloaders nest was great for window shopping for load ideas but some of those loads where grossly over speed hyped in my experiences. If I had a pc and not a Mac I would get quick load I hear it has great data and people that have it tell me it can save a lot of time and experimentation with load development.
