Well the rem 700 action is copied andused by a ton of benchrest shooters, kinda the goto.

While I'm not disputing a controlled feed can be accurate, I think it takes more work to make a controlled feed very accurate than a push feed.

It could be the flip of a coin with accuracy on a factory rifle these days I'm not sure, but to me controlled feed is for big bore dangerous game setups where reliability is the crucial ingredient, not accuracy.

And in a 7mm WSM, I think we're talking accuracy, not dangerous game reliability.

But if someone else has the kimber montanas....I'd be curious to know what type of groups they're getting. 1.5" ? sub MOA? less than a 1/2MOA?
In addition, in a recent gun test, they tested the new model 70, worst or at the bottom of the list in the accuracy department, they probably tested the kimber, should relook, but none the less, only further reinstates the controlled feed vs. push argument.

Personally I expect sub moa out of such calibers, so if I was talking 1.5" with a controlled feed, vs sub MOA with a push, id take a push hands down. And why not? there's no reason to HAVE a controlled feed in this setup, less you're planning to hunt lions?
