.300 WSM

[Classic]

Gentlemen-

I'm building a custom rifle off a Remington 700 donor action I have, and was set on using .308. However, I had the opportunity to shoot a .300 WSM using the same stock, scope, action, barrel, that I have. I enjoyed it, and was very happy with it. However rounds are a bit more expensive and seem to be harder to come by. Rifle will be used for shooting steel/paper at 100-1000 yards. I plan to reload custom loads, regardless of choice.

I am basically asking if anyone has any advice, experience, or recommendations.

Thank you.
