I am new to reloading and have been reloading 9mm only for about a month now. when I first started reloading I went to a gun show and one of the vendors there had some 9mm x-treme 115gr copper plated bullets for what i thought was a decent price so I bought 500. All 500 loaded and shot fine through my glocks, sig and my m&p. My question is; are the X-Treme bullets a decent bullet for plinking for different calibers as well such as 40s&w? Wanna kill these ads? We can help!
