I'm looking to get in the group buy at powdervalley and have a few questions. Does anyone recommend using berrys bullets for 9mm? If so what powder would you recommend? By doing a little google searching a found win 231 is recommended. Is there any reason not to use it? Also if I start doing competitions what bullet weight should i use? I might shoot .45 in the future, would win 231 be fine for it as well?
