So other than changing bolt heads & barrel, is there anything else I'd need to change on a Stevens 200 to convert from '06 to 7 mag?

I've just picked up the rifle & have a hankering for a skinny magnum. No particular reason other than I don't have one!

Is there any other chambering you'd recommend to scratch my silly itch? I've already got a couple of 6.5s that cover 99% of my hunting needs & .308 & .223 that covers everything else...
