Daryl,

you are right.

This might be a 9.5x47R.

from the http://www.skydevaaben.com/husqvarna/model33/info.xml site:
"The Model 33 is said to be manufactured between 1877 and 1912, and the slim octagonal barrel was chambered for quite a few calibres: 6x36R, 6,5x42R, 8x42R, 8x57R/360, 9x47R, 9,15x57R/360, , 9,5x47R, 10x47R, and 10,5x47R. .....
The rifle featured in this section is chambered for the 9,15x57R/360 cartridge. This cartridge is perhaps better known as 9,3x57R/360, or even .360 2 1/4'' Express. "

According to COTW:
9.3x72R (and 9.3x5R/360 and many others, similar but not quite identical to .30-30) has rim diameter of .482, base diameter of .430.
9.5x47R (and probably 10x47R)) has rim diameter of .583, base diameter of .513 (with recessed "Mauser-Boden", as in the .43 Mauser.
