I would have the rounds facing away so I can beer can grip the mag for reload
I don't know what a bear grip is.
Almost everyone (at least that I know) has their mags positioned nose first because that is the more natural way to draw and immediately reload.
Reach down, grab mag, rotate up, reload. You can do either a tea cup reload from the base of the mag palm down or turn your hand outward grab the body and rotate it back as you come in for the reload.
