The concern with larger bullets in the .338 Fed. is that they will eat up too much powder capacity, reducing performance to sub-par levels. The .338 RCM takes direct aim at this supposedly weak chink in the .338 Fed.’s armor. Hornady’s two initial offerings will be a 200-gr. SST and a 225-gr. SST, which Hornady says will exit the muzzle at 2,850 fps and 2,710 fps, respectively.

How much of an advantage will this give the .338 RCM? It’s a good question. The real measure of success for a new caliber is the number of rifle makers that pick up on the chambering, so we won’t be able to accurately judge this for another couple years.
