"Bigger holes would be better, I would think."
I agree. That is why I like the 11.5 mm .45 Colt.
Many will choose a SWC or even a WC or an LBT design that has a decent meplat, aka flat nose, over anything else, including a hollow point. Most/many hollow points will not even expand if there is a barrier between the bullet and the target. That is why Hornady puts a polymer in the hollow point, i.e. critical defense, so that it will not fill up on its way into a target and will expand reliably. Ball ammo tends to slide on through,whereas a meplat will cut and crush its way through a target. Expanding ammunition will have far less penetration, as opposed to a flat point, and if it does not expand, as often happens, it will act more like ball ammunition. There is an issue of collateral damage, but that will occur with a miss which is even worse. LEOs or anyone for that matter, miss all the time, sometimes much more than they hit. An expanding bullet that fails to expand can cause collateral damage as well. If you live in a rural area, and have many/unlimited safe lines of fire, a decent meplat will work for sure. None of this is simple. I like wad cutters for self-defense. As far as hunting goes, expanding bullets at high velocity cause more tissue damage. But when encountering dangerous game a non-expanding bullet with a serious meplat is always the best option. One six foot wound channel is better than six one foot would channels. For most people, the best expanding ammunition is the best choice. But most of the "logic" used here assumes a 100% hit rate and that 100% of the bullets will expand, which is unrealistic.
