Could someone who has reloading software answer this:
What would the difference in muzzle energy be when comparing a 148 grain .357 dia. bullet to a 180 grain .357 dia. bullet loaded to the exact same velocity? (in this case subsonic and fired from the same gun.) I am not concerned about terminal effects, just the energy difference. Assume that everything in the equation is similar except for bullet weight. Thanks for the help. |

Here's an on line program you'll like -
http://www.hornady.com/ballistics/ballistics_calculator.php To answer your question more directly, the change in energy with identical speed and powder charge for the question you posed is simply the ratio of the weights of the bullets. The 180 grain bullet has 180/147 = 1.22 times the energy carried by the 147 grain bullet. |
