I have a question for anyone using Lapua 243 Win brass. Lapua states that their 308 brass uses small rifle primers. Does the 243 brass also use small rifle primers, or does it use regular large rifle primers. I was thinking about buying some Lapua brass for my 260, and I think that having brass with small rifle primers would be nice since you can load the brass a little harder. Buying the 243 brass would be a lot easier to turn into 260 brass since only one sizing operation would be needed. But if the 243 brass has large rifle primers, then, in my opinion, it would be worth the work to size the 308 cases down to 260. Thanks in advance for the help.
