Re: Help me decide which caliber for my WSM build? ;)
I love my 7WSM so I'm a little biased. It really comes down to what you plan on doing with the rifle. Is this a hunting or range gun? If for hunting (which I'm guessing it's going to be considering this site), what type of game? What kind of range are you looking to shoot at? Do you reload?
If you don't reload, I'd say the 270 or 300 simply because trying to find 7WSM in factory ammo readily available is a pain for some reason (this was a major reason for me learning to reload). This would also rule out the 6.5 or 338 since I don't think (not positive, but pretty sure) anyone makes factory ammo for them. If you do reload, there are more options for good bullets with high BC with the 7 or 6.5. There are some bullet manufacturers coming out with new high BC 270 bullets, but there are a lot more for the 6.5 or 7.
These are just my opinions, there are plenty of people I know who love their 270 or 300WSM's. I'm sure many will disagree with me, but it's kind of like asking the old ford/chevy question. They are both good but it all comes down to is personal preference.
