relining to .25-20 is the easiest and cheapest and you get a nice little rifle. .22 Hornet would be the next easiest and ditto.
If those are TOO little for your projected uses, a .357 is a lot of rifle in a little space. Deer/pig killer at woods ranges.
I've had many of these, including a .218 Mashburn Bee. Think I like my .25-35 the best, although it is now mostly a handloading proposition.
(People don't seem to leave .30-30 cases all over the place for .25-35 lovers like they used to....and Martini actions aren't $9.95, either. Time marches on and I seem to have two "straw feet"!)
