I just got some lapua brass for my 308 and I have never used the lapua brass before. I have always turned the necks of the other brands to get uniform thickness the lapua stuff is already uniform but it is a bit thicker than what I usualy use will I get much change in velocity by not turning the lapua brass? I use a redding bushing die to get uniform tension on the neck should I just get a bushing that is a few thousants bigger?
