this is probably a dumb question, but here it is anyway. how do you tell a live shell that has been reloaded, my father reloded a batch of 300 win mags, years ago. then after shooting some, he had a casing jam in the barrell and had to send the gun back to the factory to get it extracted. the letter they sent him in return said that he had gone way over the powder grain specs for that load. any information would be helpful. thanks |

FYI, factory ammo is often loaded with powders not available to reloaders, and even if it was with a standard offering powder, it's pretty much impossible to tell what powder they were using. So just for your information, weighing the charges and trying to make a comparison will do nothing for you. Just because the charges weigh the same, or even less, doesn't mean that the reloads won't destroy your rifle.
Pull all the bullets out of the offending rounds, and start over with the brass.

Thanks for your help, I have found the offending shells and will dismantle accordingly. I looked for all the tell tale marks you all had posted and went at the shells with a micrometer and found finished height variations beyond what a normal variation is. Bullets were seated with almost a millimeter and a half overall difference. when I disassemble I will check the grains of powder against factory, then see where he was on the hotload chart. Thank you all. |

First is primer color. Depending on manufacturer, some use nickel plated primers but some are brass colored. Almost all reloading primers are nickel plated. Crimp, factory crimp is mostly unique. Bullet, Hornady, Sierra, Speer, bullets are different than Win, RP.
Pressure ring, once fired ammo will have a distortion near the base of the case where the case has expanded from being fired, factory ammo will not have the pressure ring mark. Headstamp, on fired ammo the headstamp might be flattened, have a mark from the ejector or the case rim might have nicks from the extractor.

Do you have the gun and ammo...and are you considering using them? Do you have any information on what type of powder and the load he used? |

How much ammo are we talking here that you are questioning?
