dissasembling commericial ammo

[metalliman545]

have any of you tried this to make sure every round has the same amount of powder and bullet weights? or sorted them out?
like say you have 11 cartriges, and out of that 3 bullets at 55.2 and 8 at 54.9
would you then measure the powder out of the 8 54.9grain bullets to get them as close to each other as possible just to try n get the most out of your ammo? im thinking of doing this when i get home and comparing the results.
idk just something i was wondering, im in iraq and have a lot of time to think of weird things to try when i get home.

I have never tried this. My guess is they would be pretty close to having all the same amount. Commercial ammo is made on big machines and they probably have pretty accurate powder measuring devices.

It takes a lot of time to pull rounds and isn't very fun, so I think I would just shoot them.

If really accurate loads is what you need, I'd just load them myself, or pay for top shelf rounds.

Just my opinion.

Reloaders do it all the time, but not with commercial ammo.

well yea i know that i bought a bunch of federl m193, just for plinking, i was just curious. i started reloading when i was home for R&R only made a few rounds just to get the feel. nothin serious. i know our m855 is kinda consistent, but weve found more then just a few rounds with primers missing outta the thousands wed fire at the range

NO DISASSEMBLE!!!!

(yeah, I know, dating myself a little)

I've never done it on factory ammo, but I've done it on a few of my reloads here and there. Turns out the powder drop (my biggest concern) was within 0.1gr of my target, so I stopped doing it. Now, I just weigh powder charges every once in a while before seating the bullet.

Yep. And replaced with a better quality bullet. This is commonly called "mexican match" ammo. Factory ammo has huge variations in powder and bullet weights. It used to be economical to do, maybe not so much anymore.

You also have to remove the decapping pin from your sizing die and resize (at least) the necks to make sure you get consistent neck tension again after disassembling them.

I pulled apart some BHA 175gr 308 Match ammo and found a .8gr powder weight variance within a single box of 20.

Commercial ammo will not be as consistant as decent quality handloads. Also, be warned that commercial ammo does not use canister grade powder. It may look like a powder that you are familiar with but, it can have a much different burn rate. They buy powder by the train load, test each batch and develop different loads for different lots of powder.

I don't shoot my M-A a lot, but when I load for it, I want the ammo as precise as I can make it for all the time and trouble it is to get to the range. I load each case to 40 gr., then trickle the final grain.

on the commercial powder by the train load
