It's been over 15 years, since I've owned a 77/22 Hornet - so I can't recall if Ruger simply changed the 77/22 bottom metal for the longer Hornet mag, changed the front half of the 77/22 bolt from RF to CF, and moved the 77/22 bolt stop further back - or if it was the same/different(?) action as the 77/44, I also once had long ago.
CRS can be a PITA.
