[QUOTE="grit, post: 608555, member: 4112"] Often, while reading about somebodies new big bore, I find myself thinking, "I could do the same thing with my... much smaller whatever". It is very possible to shoot the same weight and type bullet across several calibers, even from the same case, same velocity. For example a 180 in a 7, 30, and 325 WSM. I'm well aware of the BC differences, this isn't my question. Assuming same bullet weight, construction, and impact velocity, what effect does the larger diameter have on terminal performance? Presumably the smaller diameter has greater penetration, while the larger diameter creates a wider wound channel....mabey. I realize there are no degrees of dead, and the discussion is purely academic. Still, I'm interested. Many of the big bore calibers seem to operate precisely this way. Shooting the same weight bullets as smaller diameter counterparts. The fans of these cartridges all claim impressive terminal performance. I regularly shoot small calibers for the application, as well as arrows and handguns with large diameters and low velocity / energy levels. My only negative experiences have been due to my shooting, as far as I can tell. [/QUOTE]
