Eagle338, my reasons for going from a .300 Wby to .300 Win mag are as follows and they're in no particular order of importance:

- The .300 Win mag is close enough in performance to the .300 Wby that I would never, ever be handicapped by the slight difference.
- I've put close to 1000 rounds through the rifle and I just want to try something else now.
- I really like Lapua brass and they don't make it for the .300 Wby as far as I know.
- With the .300 Wby's considerable freebore, I can't seat bullets close to the lands. I want to be able to seat a bullet right up close to the lands if I so desire.
- Just in case I were to forget my handloads when I go hunting, I believe .300 Win mag ammo would be easier to find in stores.
- I like Redding Competition seater dies and the .300 WbyComp seateris too long to use in my Forster Co-Ax press. However, I believe the .300 Win mag Comp seater will work in the Co-Ax. At least I sure hope so anyway.
- I'm just not too crazy about how that double venturi shoulder on the Wby cartridge looks and I don't think it serves any useful purpose.
- I tend to think the .300 Win magcartridge is a tad bit more accurate, though I don't have any personal experience to back this up.

Well, that just about covers it. If you were really interested in gaining some knowledge about my thought process, then I hope this helped.
