This is not an easy fix! Find a gunsmith who can deal with the problem. And believe me, it can be a problem. Center feed is the best and easiest cure, problem is, nobody I know of makes any aftermarket magazine parts for the Rugers. Might check and see if someone, like CDI, makes detachable bottom metal where you could use AIC magnum magazines. Even those may have feed lips that are too short to control the WSM. I won't do a conversion, any more, to WSM on any action not already designed to use WSM cartridges already. It's just too much bother and takes too much time, and I'm never really completely satisfied. I can make 'um work,, just not as slick as I'd like. Got too much stock work to do to mess with stuff like this. The WSMs are way over rated, IMO, anyway. "A marketing ploy by a dying company, that died anyway" (even though I do own reamers)
