I'm planning on switching to 7saum for my F-class rifle. I would prefer to just switch entire bolt entire bolt assemblies, rather than just the bolt head. So far, the only place I've found that has a short action right hand magnum bolt is Midway. But, they only stock the controlled feed bolt. Oddly, they stock the push feed in left hand only. My question is this: am I sacrificing any safety or accuracy using the controlled feed bolt? Or, is the push feed the way to go?
