RE: Custom Rifle what action would you choose and why?
I would choose a Model 70. Have had so any over the years, as well as Remington, Savage, Browning and the Model 70's just shoot smooth and accurate. Also is seems fewer mechanical issues.
Winchester is however downsizing quite a bit and some of the newer after market parts have been problematic.
My second would be Remington 700 BDL.
