I don't know when it changed but Savage short actions were always designated as a two digit model number, i.e. model 10, 11, 12, 14 and 16. Long actions were 110, 111, 112, 114 and 116. Now they list 110 models, like your Storm, in long and short action chamberings. I don't think Boyds have sorted that out yet. If you configure one of their stocks as a model 10 bottom bolt release then you have a choice of a "Left Hand Bolt, Short action, Detachable Magazine". If you're interested in one of their stocks it would be worth a call to confirm fit before ordering.
