The older H&R rifles (rifle/shotguns) models 58,058,157,158, and 258 (and probably others) were made in 22 Hornet, 22 Jet, 30-30, 357 mag, 357 Maximum, and 44 mag. Other models were made in 45-70. The earliest models came w/o a transfer bar and in both slim and full receiver/barrel sizes. The later models, late '70 to '86, had transfer bar "safeties". Some of the models came with a accessory shotgun barrel, usually 20 ga. I have several of these different models and all are greal utility guns, accurate and reliable. The Savage 219/220 series came in 22 Hornet, 25-20, 32-20, and 30-30(also with accessory shotgun barrels availiable in 410, 20ga, 16ga, 12ga and maybe others). The Savage is hammerless in design and was somewhat heavier and longer than the H&R's. The later ones had provision for scope mounting. I've had several of the Savages, but prefer the older H&R's (handier). I've had no experience with the Rossi. Hope this helps.
