need reload help
HI guys I' m new to reloading and I have a question for ya,I just bought some reloading equipment and started reloading.After I was done doing about 40 123 gr 303 cal rifle bullets I realized that the powder they gave me was dupont 800x.when I looked up the brand on the web it says it is suited for heavy shotshell loads and heavy pistol bullets.Is this going to be a problem in a rifle.Any help would be great.
