It's that simple. I've resized several different brands for a custom 358 Win built on a Mauser action. I've found that for some reason I get better results with the Federal brass. I don't know if it's harder, or has a slightly greater case capacity, but loads which show pressure signs with Winchester brass don't do so with Federal brass. I just shot an eight point buck last Saturday with a 200 grain Hornady spire point. Through and through penetration, good blood trail about 40 yards and down. No ruined meat. When resizing be sure to use plenty of lube on the inside of the neck to avoid stretching your brass and be careful about pushing back the shoulder. This works well with both the 358 Winchester and it's mama the 35 Whelen. There will always be plenty of 308 and 3006 brass, so don't worry.
