I have heard from several sources that it is hard to find an accurate 7MM WSM but have heard many times about the superb accuracy of the 270 WSM. Has anyone had experience with either of these rounds?

My Rock barreled 7mmwsm is more forgiving easier to shoot and less finicky than my Krieger barreled 270wsm as it should be. The 7mm is a FN wsm SPR action with a Rem Varmint contour barrel over 10#'s. The 270 wsm is a hunting rifle model 70 classic featherweight action with a light sporter weight barrel under 8#'s. I think if you use good components and have a smith who knows how to run a reamer there will be no difference in like rifles in these 2 calibers.

IMO the cartridge has very little to do with the accuracy of a firearm. It's much less important than many other factors such as the barrel, the action, the bedding, the trigger, the barrel crown, the bullet, the workmanship of the gunsmith, etc...

I highly doubt one will be more accurate than another, maybe they are forming 7mm WSM brass from .270 WSM. The only thing that would keep me from buying the 7mm is it seems to be out the door already as far as popularity/availability. Just stock up on the 7mm brass if you go that route, I doubt you'd be disappointed.

neck down 300 WSM, no probs
