so i picked up 50rds of .50 BMG API,.. the cases are a mixed lot of LC 53..(the brass around the head stamp looks pretty beat down)..LC 87,.& LC 84.
it seems that there are alot of rounds that have there canilure more exposed than others,.. most rounds have a C-OAL in the 5.42 to 5.46 range,. but one or two that go as low as 5.33 & as high as 5.55,.. i am thinking the short rounds may give me a problem out of my m82 because of overpressure,. and the long round i just do not know..... there are a few rounds that do not have the silver tip like the rest of the API,..i know that sometimes the paint gets removed or is very hard to see,. but these rounds do not look like they ever had a painted tip on them,.. and one of them looks like a really dim faded black color,.. so is it normal to get mis-matched ammo? i do not know the manufacture for these rounds,.... they where pulled out of a 50 cal can and put into a cardboard box,. i asked about the headstamp and i ws told Lake City,.. which it is,.. but i did not think they where reloads,. i figured it was de-linked MG ammo,. it was not until i got home and took a closer look at them that the flags started going up. so i am not being a OCD-ish nit-picking bastard for being concerned about this am i? i am thinking i need to call the shop i got these from and get some answers. |

They sound like reloads to me. If you can take them back do it.
An 82A1 cost around $8500.00, a new face a bit more. Not worth it to save a few bucks on ammo. The only other way to get piece of mind would be to pull some/ all of them down, check the powder type and charge and reassemble. my.02cents |

Most likely reloaded ammo. I won't shoot reloads in any of my guns, especially my 50 unless I loaded them myself or know who did (a licensed reloader). The OAL variation of +/- 0.03 isn't going to hurt anything. It's just if you don't have confidence in the ammo, you shouldn't shoot it. Are the primers silver colored or brass? If they're silver, it's almost definitely reloaded. The black colored bullet tips are M2AP, the predecessor to AP. They're armor piercing, just not incendiary. They're actually more useful than API because they don't start fires. They won't shoot to the same point of aim as API because they're 700 grains instead of 630ish of the API. Here is a case where being a member of the FCSA would do you more good than a membership costs. There is an article in the VHP this issue ALL ABOUT identifying corrosive vs non-corrosive ammo, reloaded surplus from factory surplus, etc. The article is heavily into pictures and shows just want to look for to tell factory from reloads. Another good reason to join FCSA. -David Edgewood, NM |

If the primers are brass then they're probably mil-spec and not reloads. There are different manufacturers of projo's and that will give you the variences you're seeing as they get crimped to the cannalure. Not all the projo's are the same when made, just kept to within certain dimensions.
If they are true mil-spec then they'll be a little bit hotter then what you normally load as they're loaded for an M2. My biggest concern would be how they've been stored over the last 20+ years. |
