Is it necessary to trim brass when reloading for .357 Mag ? I'll be using new Starline brass. The dies I’m using are the ReddingTitanium Carbide Pro Series with a Profile Crimp die. I measured about 30 random samples, and most were either 1.281 or 1.282" long, with a couple measuring 1.279 & 1.280. I did find one sample that measure 1.287". These will be fairly hot loads using W296, Hornady 125g XTPs and Nosler 180g partition bullets.
If trimming in necessary, what tool do you use ? I have a Wilson case trimmer and a Giraud trimmer I use for my rifle cases. Thanks.
