[quote]The Ruger MK-II action is not a true CRF action though. Look at it the next time you feed a shell and notice that the bolt on the Ruger does not hold the shell within the bolt face. Therefore, if you were to turn it upside down during feeding a shell, it will fall out.
I' ll worry about that next time I shoot my rifle upside down... you never know it may happen someday.. I can also feed a shell into the chamber and close my bolt over it without messing up the extractor something a Winchester cannot do. .No the Ruger safety is not part of the bolt ...it actually locks the firing pin and sear at the same time in full back position which makes it safer than the Winchester. It also can handle a ruptured case much better than any Winchester exiting the gas thru the magazine thru some pretty substantial slotted holes . Hmm when did I ever hear that pre64' s were tack drivers perhaps good shooting guns but tack drivers because of the cut rifling... seriously now. The pre 64 is a good collectors piece that belongs in the gun safe . If your going to build a custom rifle the newer MOdel 70' s are much better choices...
