i have a 110 in 300 win mag center feed.. what size calibers can i change to with only changing the barrels?? i realize that i may not be able to use the center feed mag so it will be a single shot..(i think). any body have any info that would be great.. is 30-06 an option??

if anyone has any barrels in good shape for sale let me know thanks...also need a nice stock..


thanks for the info.
