With Lapua brass being hard to come by right now I picked up 300 pieces of starline .223 brass for a varmint rifle build I'm working on. I have a .248" redding neck bushing for my Lapua brass. The starline seems to be a little (not much) thinner neck. Is anyone using a .247 or .246 bushing? Is there a need to turn the necks?
