eagle, I had blind magazine rifles and went away from them because of the cleaning and unloading. I, unlike your good self, don't take the rifle out of the stock unless I really have to. The cleaning of dust, debris, mud, snow etc while hunting, the hinged floor plate works best of the two. When I get home is the only time I will remove a stock and only if I don't think it is really warranted. Mind you most of my rifles are Ceracoated and synthetic stocked. Those that are not ceracoted I rub Gilly Stephenson's Gun wax/polish into the timber and all metal parts. Yes, I am becoming lazy in my old age.

I was sold a replacement and supposedly better hinged floor plate for my Rem 700 in 35Whelen. Like you said, it undid on the first shot. Threw that away and put back the bog standard Rem floor plate, no further issues.
