Recently, I started reloading the .300 RUM, using Nosler bullets and new,bulk, Remington brass from Midway. Upon the first firing, I had 2 split necks out of 20 rounds. Forester BR dies were used. The brass was very close on wt. and length before loading. Is this to be expected with this round, or not? Maybe Nosler Brass would do better?
