The .32 special is pretty much interchangeable with the .30/30 as far as performance goes but the .30 is much easier to feed than the .32 nowadays. They originally designed the .32 Winchester Smokeless(.32 special) as a round that was sold as smokeless powder loading and could be reloaded with black powder(weren't really sure this new fangled smokeless would pan out). The .32 had a 1in16 twist rifling versus a 1in12 twist for the .30/30 to reduce fouling, larger bore and lots of .32 cal. bullets molds etc. were on the market owing to the success of the .32/40. There really is no difference between the two in effectiveness on game that I have seen, I've shot deer with both. My grandfather was convinced his .32 special hit harder up close but the .30/30 "carried out" better at longer range. Years ago older guys would almost come to blows arguing about which was better at our camp which is pretty funny.
Hazarding a guess; you are also a 'Pet Loads' fan, lol. That isn't a direct quote, but you can see it likely came from that tome
