I have had a few custom rifles on rem 700 actions, and I also have a CA ridge line in 300 WM.
The customs with high quality barrels, chamber right, will out shoot my CA. I just put the CA in a new stock and glass bedded it. Plan is to shot the CA and my Rem 700 6.5-284 Brux barreled rifle side by side to see which one is better, now that I have the CA glass bedded in a stocky LRC stock its a better comparison to the 6.5-284 that's bedded in a BC stock. Up to this point, before bedding the CA, I have more confidence in the 6.5-284. The Ruger done right would be a darn sweet gun for sure, But I doubt you could out shoot yourself with it against a CA in 7mm Rem mag in a hunting type situation.
