Most of you all probably already know this, but for anyone who doesnt; beware of all the reloading data you see on the internet. Double check it with reputable sources. I found some misinformation on AMMOGUIDE.COM myself. After contacting them they didn't seem to concerned. I called Hornady and got the correct information. I am inclined to go with the Hornady information, since they developed the cartridge. The .375 ruger!
