Welcome to the sometimes confusing world of firearms, and Shooter's Forum, burfniner.
Today, there are no rimfire cartridges made larger than .22 caliber, other than an occasional run of .32 RF to satisfy the owners of older rifles so chambered.
100 years ago, there used to be a .30 caliber rimfire, but it was a short, revolver round - and not the world famous .30-30 Winchester centerfire, which was introduced even earlier - ca. 1895, IIRC.
100 years ago, there were also Marlin rifles chambered for the .32 rimfire - but that was a much smaller actioned gun than a Model 336.
