[QUOTE="KH_Outdoors, post: 2649186, member: 123559"] Currently have a 338 Norma (standard) and using Lapua Brass. I have noticed on the Norma that the case grows a little more than 30-35 degree cases. Especially on first firing. Maybe plan to trim every 4-5 firings after initial? I shot the virgin brass after just expanding/chamfer/debur. Then trimmed everything to same length and have put 4 firings on the current lot since trimming without having to trim again. Not too bad 👌🏽 I don't mind trimming cases on occasion for the Norma. Being realistic we don't shoot big 300/338 Norma's hundreds of rounds at a time (at least I dont). So taking a few minutes to trim every few firings hasn't bothered me yet. [/QUOTE]
