The answer seems obvious, but one thing I learned about reloading is ask first instead of pulling 100 rounds because you had to post one of those "what did I do wrong" threads.
For the first time I get to load new factory brass (Remington for the 300 RUM). I've so far only started out with factory loads, and then reloaded. Is there any reason to run the new brass through the sizing die first?

As I get older I find hitting a mini ram at 200 yards with the 22 oddly more satisfying.
