I noticed that Taylor mentions the Colt 38 auto (38 Super?) A number of times in African Rifles & Cartridges. He seemed to prefer that over the 45 Auto and being a big bore advocate, why would he do this? When both are loaded with FMJ bullets, I would think that the 45 Auto had the advantage. With the FMJ, how much 'real measured' difference is there in penetration and knockdown?

How would you folks out there measure them up against one another? What if you could include the 45 ACP +P loadings into the mix?
