[QUOTE="Aussie, post: 127192, member: 2447"] Read somewhere that 7mm Rem. magnum brass can vary up to about 10 grains in internal capacity from one manufacturer to another so be careful .Also may find if loading for a magazine fed factory rifle that the 7mm WSM won't do as well as the Rem. with heavier projectiles due to requirement to seat long projectiles back into the available powder space . No flies on a 160gn projectile at 3000 FPS with H4350 but in my experience the 7mm WSM works better with slower burning H4831SC and Reloder 22 . Magpro is worth a look too but no personal experience with it . [/QUOTE]
