barm: Hunter is right about using cast bullets at slower speeds for harvesting table game and both the 32 H&R and the 32-20 are fine small game calibers. I would start with the cowboy loads to see how they shoot and what your barrel looks like after about half a box...
There are many ways to lead up a barrel: soft slugs at high speeds, soft to medium slugs with powder that burns too fast, even hard slugs over low powder charges that do not let the bullet obdurate to the barrel. Either of the two calibers mentioned will shoot tons of cast slugs without leading if you put your loads together properly and I have to recommend that you cruise on through this site and down into the Handloading Forums to Veral Smith's Forum for more information on leading than you can probably digest in one sitting. There has been lots written on this topic, far to much to adequately recap in one post. It is a very informative read.
In fact, I have been thinking of asking Veral for some sort of a design for a 30 caliber pistol bullet that is either akin to the new LBT designs - nice wide flat nose, or a Keith style semi-wadcutter that could be used in the 32 H&R, even the 32 short or Long, the 327, the 7.65 Luger and the 7.62x25mm. I'll just have to put my thinking cap on and run this by him to read what he says about it... Hope this helps.
