I imagine so. All the round receivers ala Rem 700 are so for streamlined manufacturing process, not because they are better IMHO.Interesting point.
Would round stock used for an action first be forged, and then machined? I have no idea as well. There has to be a metallurgical engineer somewhere in this community that can take us into a far too detailed discussion about processes as well as the pros and cons.
I never had an issue with 2-pos wing style safety on either side of the bolt shroud. But they are pretty stiff. Soft safeties I do not like as they do tend to switch from one position to another as if by magic during any handling. I can't speak to the issues people mention either. Obviously if they don't like them for the safety potentially moving in the brush it must happen. In the brush I prefer to have my gun in my hands anyway, but we all hunt differently and I'm sure there are situations where branches may poke the lever. But the loading unloading I do not get. With Mauser style action you just lift the bolt and move it back and forth. With cock-on-open the firing pin is back in the bolt body, so quite safe, I think.I took an 8mm post WWII Brno vz.24 and made it into a 404 Jeffery. Military flag safety is fine for combat soldiers with unknown or limited experience with guns. But for hunting they are not for me. Too fiddly. It's a two finger task moving the flag from right side to left side of the bolt shroud. Leaving the flag in position two straight up is not a good plan when stalking. The bolt can pop open accidentally. And, of course, flag safety doesn't work with a scope. Wing style aftermarket scope relief safeties are two position only. Be aware that some of those will disengage if the bolt is rattled. Also, if the scope is detached for optional iron sights, the wing safety is then vulnerable to being accidentally disengaged in the safe position. So I opted for aftermarket 3-position Model 70 safety. Those are tough to beat. Out of the way and 3-position so the gun can be loaded/unloaded with striker locked.
I mean anything can happen when we mishandle a gun...so to each his own probably.
