I was just wondering how much improvement in accuracy at long range is achieved using Norma or Lapua brass. I have been thinking of buying 100 of the Normas but they are a little over $1 a piece. I could buy 200 Winchester cases and sort them out and still come out with probly at least 100 good cases and still save money. I have always just used Remington Nickel brass because I like nickel. Never really thought about the brand much. But I have found that all the LR hunters, 1000 yard and target/benchrest people use Norma or Lapua brass. I also seen the Sierra manual where the guy preaches about "brass is which accuracy flows" or something to that sorts. I would only be shooting out to 800 yards for practice, and my limit on deer size is 600 yards. I shot 800 yards 1 time, 3 shots and they were all in a vertical line 13 inches, about 4 inches apart from each hole. That sucks and discouraged me from shooting that far anymore. I was wondering if brass had anything to do with it and if Norma will help that? I'm not to sure, but I want to start shooting 800 yards a lot more and I want to look for better groups than 12-13 inches and hope for them not to be in a vertical line. So maybe Norma brass since its a lot better and all the LR shooters use it, it might help a little is all im thinking. Thanks in advance.
