Kute , maybe you did not mention feeding issues , but Brad did .

And your right , I don't know any more about feeding of an RCM cartridge than anyone else , but I do have some faith in Ruger producing a rifle that will feed and function.....IMO they have a good track record in that respect.

As for the magazine capacity , my take would be that if one or three shots do not sort out an unexpected grizz problem , a fella would be in deeper dodo than a couple more shots is gonna help........but I'll defer to your experience when it come to extracting one's-self from grizz dodo......
