Not sure don't quote me but i think Peterson will this year.But they won't make 300WSM, go figure!
You have some lapua nm cases on hand? Mind giving a load neck diameter? ThanksView attachment 1032339
300nm brass can only give me 5-7 firing..been (torture) testing a necked down 423 dakota lapua brass to 300nm.i load them sometimes till i get ejector marks or flat primer...15-17x so far still tight pocket...im pretty confident that 300nm lapua brass going to be strong
Alex, based on a small sample I have here at my desk, both calibers are running right at .015". The 338 seems to be a bit smaller, running .0145"-.0150". First run, but they should all be right in this ballpark.
