[QUOTE="Buck Fever, post: 1886961, member: 113501"] I'm sure I could load 10mm quite a bit hotter. I kind of doubt much is left on the table with those 460 Rowland numbers. Also 10mm holds 15 rounds to the 460's 13. I look at a 200 grain 10mm. You can find good and tough 200 grain JHPs for 10mm and if you get it moving it will mushroom and penetrate. I can't see the numbers on this page but I bet it has sectional density better than a 230 grain .451" bullet. What do you think 230 grain .451 bullets are made for? If you said a .45 ACP with about 850 fps muzzle velocity, you are right. If you run it at 1350 fps, what do you think it is going to do? Fragment like a varmint bullet is my guess. A hard cast lead might penetrate in a 460 Rowland but it's not going to expand much. Numbers can tell a story but they can leave some important details out. In my mind, velocity and sectional density lead to penetration unless your bullet expands or fragments. I know that certain loads for .475 Linebaugh can do 48" of penetration through the skull and head of a bull elephant. It sounds great but unless you shoot a bear lengthwise, a lot of that is going to get wasted so there is a balance and I would want penetration with expansion, dumping as much energy as possible and making big gaping wound channels. Does anyone have a ballistic substitute for bear? I bet its tougher than ballistic gelatin but if you can't test your penetration, expansion and weight retention, you are not seeing the story the numbers dont tell you. [/QUOTE]
