7 WSM 1000 yd rifle.

I was under the impression 7mmWSM only gave a slight velocity advantage over the 284 Win but with much lower barrel life?

And since you already have a 284 you wouldn't really need the 7mmWSM?
Unless you just want it then "need" doesn't really matter.

Was also under the impression 7mmWSM was in hot pursuit of 6.5x284 for benchrest stuff, but then 284 Win came back on the scene and knocked it's popularity back a bit.
