The 150gr scorocco has more energy because the equation for energy uses Mass x velocity with the velocity squared, so any high velocity round will have a very high energy as well even out to 500 yards. It works out so well for the 150gr scirocco because of its' very high ballistic coefficient and therefore maintains it's velocity even out to long range. |

Energy figures are just a number, and don't mean much. The heavier bullet WILL "pack more punch," regardless of what the energy figures show. The heavier bullets also have a higher ballistic coefficient, and therefore retain their velocity better than the lighter bullets, and for that reason they are also less affected by the wind. If you like the Scirocco that is fine, but if it's available in a 160 or 175 grain version, you will find that it will perform better than the 150 grain, especially on larger animals like elk. The 150 grain is what you would want to shoot out of a 7mm/08 or a 280 Rem. The only reason to use a bullet that light out of your magnum is if you can't handle the recoil you will get from the heavier bullets. |
| GoldTip:
Bobcat, the LONGER bullet for diameter will have a higher ballistic coefficient, not necesarilly the heavier bullet. Yes, a 160gr scirocco for the .284 caliber would be almost both ballistic and energy pure magic, but they don't make them, but I wish they would. |
| bobcat:
I realize that...I'm talking about a heavier bullet in the same style bullet, having the higher BC. How about a 160 Nosler Accubond? I bet it's got a higher BC than the 150 Scirocco. |
| GoldTip:
Ya know I haven't paid much attention to the accubond to be honest. Is it a boat tail bullet? I have read a few good things about it. Ya know anyone who has used them? |
