I am guessing the last choice was .357, which is the one I voted for.
I like the idea of having a revolver and rifle being the same. I am currently looking at buying a levergun in .357. I think if you are looking for a plinking or self defense rifle caliber the .357 would be it.
Even though I voted for the .357, I would also highly recommend the .30-30 because it is so common and reasonably cheap to shoot. The .30-30 will also fill the self defense role and it has more power and range than either the .357 or .44.
Try out all those calibers listed if possible and see what works best for YOU.
