| Post subject: | 357 magnum question |
Does anyone know if i can shoot a 357 rifle round through my hand gun. winchester has one that goes about 1800fps out of the barrel is that safe to shoot out of a hand gun or is that rifle only thanks |

I'm not aware of any factory loaded "rifle-only" 357 mag rounds. What kind of gun do you have? |

Plus 1 on what Dean said. Any factory .357 should be safe to shoot in a revolver chambered for .357. I'm not aware of any rifle only .357 loads although I remember seeing some "rifle" .44 magnum loads quite a few years ago. You could also use them in a .44 revolver, they were just loaded with a slower burning powder for the longer barrel. |

i Have a S&W 28 4" barrel. Does that sound like to much powder 1800 fps? I think i am going to e-mail winchester about it and see what they have to say. I am just worried about the pressure being to great. Thanks for the input. |

Will i get less velocity is that what you are saying?? |

its the same load, just one tested in a short barrel, and one in a longer barrel. The revolver/cylinder gap and the longer rifle barrel are the reason for the difference in posted FPS . |

Ok i suppose the pressure escape is harder on velocity than the friction of the longer barrel. Thanks guys |

The friction from the longer barrel is negligible. You have to get a barrel longer than 30" or so for friction to take effect. |

Thanks guys The lower muzzle velocity out of the revolver has much more to do with the shorter barrel than with the cylinder gap. If you were shooting the .357 out of a single-shot pistol with the same 4" barrel length but no gap, it' would be a little faster, but nothing close the velocity you get from a 16" carbine. |

Okay so i am still not quite grasping the science behind the less muzzle velocity out of a shorter barrel can some one explain the mechanics behind this. Is it because the round is more protected and can get up to full potential inside the barrel before it is exposed to the environment or something to that effect. thanks |

The pressure of the expanding gas continues to accelerate the bullet as long as it is in the barrel; coming out of the gun, the speed stops increasing. |

ok i get it now. Now i know and knowing is half the battle thanks |
