Nosler is becoming my Favorite brass,,I use it in everything I can except the 338,and I use Lapua brass for it,,Nosler seems to be as uniform as Lapua but maybe not hardly as tough,,
if Nosler makes 270 WSM brass I would highly recommend trying it
my experience with Norma brass is only with 204,308 and 257 Weatherby,,I had to trash the 204 after 2 loadings due to primers falling out,,and it was not near as hot a load as I had been shooting with the factory Hornady brass that lasted 8-9 cycles
My 270 WSM load shows pressure signs in Federal brass, but shows none with Remington brass. As much as I am not a Remmy guy, most of my pet loads use their brass.
